1. Identify the longest chain, or main chain, of carbon atoms existing in the molecule. This will not
necessarily be the most obvious horizontal chain, however in our example, it is the _______________
chain.
2. If you are dealing with a branched hydrocarbon, identify any sidechains or sidegroups. Here is a list of
sidegroups you are responsible. You are given the name find out what their structure is ( pg. 13 )

Note that the prefix iso counts alphabetically but not sec or tert
2. In our example, there are two methyl groups.
3. Identify the location of the sidegroups by numbering the carbons from one end to the
other. In the example, the methyl groups appear on carbon numbers ____ and ____.
It is important to understand that the molecule in the example is the same as
CH3
CH3
CH3
H3C
because the methyl groups are attached to the same carbon numbers. In the example, we began
numbering from the left, in this case we begin numbering from the right.
Always begin numbering at the end of the carbon chain that gives the
lowest valued position for the sidegroup. If more than one of the same
sidegroup appears, assign the appropriate prefix to show how many are present (ex.
Di for 2, tri for 3, tetra, penta, and hexa). Prefixes are not considered for
alphabetical order.
4. Separate numbers from other numbers with commas, and separate numbers from
words with hyphens.
Example 1:

Properties(pg 22)
Members of the alkane family share some distinct chemical and physical properties. Due to their non-polar
nature, alkanes are _______in water. They generally have low boiling points, but boiling points
___________ as the number of carbon atoms in the molecule rises. This is due to the fact that when
more carbon atoms are present, more hydrogen atoms are present. Recall that hydrogen atoms are
bonded with carbon atoms covalently within organic compounds (intramolecular bonds). These hydrogen
atoms are constantly forming momentary and induced dipoles as the electron each one shares with carbon
moves closer to, or further away from it. These momentary dipoles help create intermolecular bonds
(bonds between molecules).
Therefore, more hydrogen atoms means more intermolecular bonds must be broken for boiling to occur,
and more energy (heat) must be added to the system.
Similar reasoning can be applied in determining the physical state of various carbon compounds at room
temperature.

Crude oil is a vital fossil fuel for modern life. It is a mixture of _ _ _ _ _ _ _ _ _ _ _ _, mostly alkanes,
that is _ _ _ _ _ _ _ _ _ by an industrial process called _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.
To start with, liquid crude oil is fed into a _ _ _ _ _ _ where it is vaporized. The _ _ _ mixture of gases
then passes into a fractionating _ _ _ _ _ _ and begins its journey upwards from the hottest region at the
bottom towards the coolest region at the top. Hydrocarbons with similar boiling _ _ _ _ _ _ condense at
different _ _ _ _ _ _ and flow into collecting trays. Each so called _ _ _ _ _ _ _ _ contains
hydrocarbons of a similar size. For example, the petrol fraction condenses at a _ _ _ _ _ _ _ _ _ _ _ of
about 40oC and contains hydrocarbons with five to ten carbon _ _ _ _ _. The lower the boiling point of a
hydrocarbon, the _ _ _ _ _ _ up the fractionating _ _ _ _ _ it must go before it can _ _ _ _ _ _ _ _ and
be tapped off.
The _ _ _ _ _ _ _ fraction is tapped _ _ _ at the bottom of the fractionating column. This material is
used in road building and as a protective roof covering. The _ _ _ fraction, used as a _ _ _ _ _ _ _ _ _
or as fuel for _ _ _ _ _ and central heating, condenses at the following level and next comes the diesel
fraction, a source of fuel for lorries and _ _ _ _. Kerosene, used as _ _ _ _ _ _ _ _ fuel, is followed by
the less well known fraction called _ _ _ _ _ _ _. This material plays a very important role in the
manufacture of medicinal _ _ _ _ _ and other chemicals. After the naphtha comes _ _ _ _ _ _, that well
known fuel for cars. Finally, the refinery _ _ _ _ _, including the camping stove fuels propane and
butane, never condense but are simply collected for bottling at the _ _ _ of the tower.
On the whole, smaller hydrocarbons are more useful and in greater demand than larger ones.
Fortunately, an industrial process called _ _ _ _ _ _ _ _ can be used to turn long chain alkanes into short
chain alkanes and equally useful _ _ _ _ _ _ _. In this _ _ _ _ _ _ _ decomposition reaction, vaporised
_ _ _ _ _ _ _ are heated to temperatures of 400-700oC in the presence of a powdered _ _ _ _ _ _ _ _ _
_ _ _ _ _ catalyst.
The alkenes produced by cracking can be made into polymers using addition polymerisation reactions. A
_ _ _ _ _ _ _ _ and high pressure are used to make thousands of unsaturated alkene molecules rapidly
join up to form long _ _ _ _ _ saturated molecules. During the process alkene carbon-carbon _ _ _ _ _
_ bonds break and _ _ _ _ _ _ bonds form. Addition polymers are commonly known as plastics.
Examples are: _ _ _ _ _ _ _ _ _ _ (used to make carrier _ _ _ _, bottles, buckets and bowls); _ _ _ _ _
_ _ _ _ _ _ _ _ _ _ _ (also called _ _ _ and used to make electric _ _ _ _ insulation, records and
clothes); _ _ _ _ _ _ _ _ _ _ _ (used to make foam packaging and _ _ _ _ ); and _ _ _ _ _ _ _ _ _ _ _
(used to make crates, _ _ _ _ and carpets). One problem with plastics is that they are nonbiodegradable, but they are often _ _ _ _ _ _ _ _ nowadays even though the cost of sorting and
reprocessing them is high.

Chemistry of Ozone Depletion by CFCs ; watch video www.teachersdomain.org Ozone Hole

CFCs destroy the ozone in the stratosphere (15 - 20 km above the earth's surface)
(Ozone concentrations are measure in Dobsen units, 1 Dobsen unit represents 1 molecule of O 3
for every 1 billion air molecules)
Ozone loss is greatest over _____________ where the ozone depletion has been recorded and is
commonly referred to as the "ozone hole".

Ozone (O3), an allotrope of oxygen, is poisonous to humans if breathed in, but is important to life
in that it filters out or absorbs short wavelength ultraviolet radiation (u.v) in the 280 - 320nm
range which can cause serious sunburn, skin cancer and eye disorders.

The inertness and lack of water solubilty of CFCs mean they are not destroyed nor are they
dissolved in rain water so they stay in the atmosphere for a very long time and diffuse up to the
stratosphere

In the stratosphere, CFCs come into contact with short wavelength ultraviolet radiation which is
able to split off chlorine atoms from the CFC molecules
CCl2F(g)

u.v radiation
--------------->
CCl2F(g)
+ Cl(g)
These chlorine atoms destroy the ozone layer
Cl(g) + O3(g) ------------->
ClO(g) + O2(g)

There are significant numbers of oxygen atoms in the stratosphere (since ozone undergoes a
natural photochemical decomposition producing oxygen atoms and molecules) which leads to the
regeneration of chlorine atoms in the stratosphere.

So, 1 CFC molecule can destroy many ozone molecules.
ClO(g) + O(g) ------------->
O2(g) + Cl(g)
Substitutes for CFCs (pg 34)

The only long term solution to solve the problem of depletion of the ozone layer is to phase out
the use of CFCs (Montreal Protocol of 1987 and subsequent modifications)

Some CFCs can be replaced by HCFCs (hydrochlorofluorocarbons), compounds containing at least
1 H atom. Most common used today is __________________________
The C-H bond makes these compounds more reactive in the atmosphere so they are destroyed
more quickly and so are less able to diffuse into the stratosphere

Hydrocarbon Derivatives
Functional Groups
Now that we have finished our look at hydrocarbons, we move on to hydrocarbon derivatives. Adding
other atoms to hydrocarbons generally forms these. Examples of such derivatives are alcohols, esters,
carboxylic acids and alkyl halides. Functional groups are the sites at which most chemical reactions occur.
They are generally polar and will react with other polar or ionic reactants, however the double and triple
bonds in alkenes and alkanes can also be considered functional groups. Organic compounds with the same
functional groups will behave similarly in chemical reactions. Some of the most common functional groups,
their general structures and examples are listed in the following table.

In naming aldehydes and ketones, locate the carbonyl carbon atom that contains the base name. For
aldehydes, remove the –e ending from the base name and replace it with –al. For ketones, remove the –e
and replace it with –one. It is important, when naming ketones, to use the number of the carbon to tell

Esters consist of two hydrocarbon groups separated by the ester functional group. This group consists of one
oxygen atom doubly bonded to a carbon atom and another oxygen singly bonded between the same carbon
atom and the next hydrocarbon chain. In forming esters _______________ is removed from the alcohol and
________________ is removed from the acid. See page 64-65
Esters have lower boiling and melting points than alcohols or carboxylic acids because they cannot form
hydrogen bonds.
In naming use the alkyl portion of the alcohol name as the first name.

IUPAC Names:
Naming of amines is very similar to the naming of alcohols. The longest chain containing the amine is
used as the root name. The -e ending in the naming of alkanes is changed to -amine, and a number gives
the position of the amino group along the chain. Other substituents on the carbon chain are given
numbers, and the prefix N- is used for each substituent on nitrogen.
