Semester Review: You can bring to the semester final a handwritten 3x5 card with any
information you wish to help you on the exam. The following ideas and words may be
helpful to you. Any or all of the following could be on your flashcards, however
remember that you may not use your flashcards on the semester final. Review your
notes, section
All Material from first semester. Safety, Unit 1, Unit 2, and all class activities.
For Unit 2:
Identify all functional groups by molecular formula and structural formula. Recognize
there may be isomers of these)
Relate smell to functional group.
R-C-O-O-H etc.
Relate different smells to functional group.
Classifying molecules. (shape, types of bonds, types of compound, polarity etc.)
Carbon Hydrogen Oxygen Nitrogen Sulfur relationships within compounds
Functional group type and characteristics such as:
Carboxylic acids and names
Ketone and name of substance
Ether and name of substance
Alcohol and name of substance
Amine and name of substance
Ester and name of substance
Reaction of an acid and alcohol forming an ester
Synthesis, synthesis reaction
Prefixes in names telling how many carbons including but not limited to:
Meth, Eth, Prop, But, Pent, Hex, Hept/Sept, Oct
Smell such as:
Iso
Putrid, sweet, mint, medicinal, fishy, fruity, floral and proper usage.
Sweet smelling include esters, ketones, and alcohols (be able to distinguish between
shape and molecule)
Minty smelling include ketones, alcohols (be able to distinguish between shape of
molecule).
ethanol, butanol, hexanol, isopentanol are examples of alcohols
ethy alcohol, butyl alcohol, hexyl alcohol, methyl hexanol are another naming type of
alcohols
acetic acid, ethanoic acid, propanoic acid, butric acid, butanoic acid, heptanoic acid
are examples of acids given in this unit
Catalyst
Lewis Structures, Lewis Dot two ways to show how electrons are being shared.
HONC 1234 bond types/bond strengths in polar and nonpolar compounds
How many functional groups have one oxygen and have no smell?
Sharing of electrons vs giving taking of electrons (electronegativity and
electronegativity difference)
How many functional groups have one oxygen and have more than one smell?
Shape of molecule, bond angles, unbonded electrons, bonded electrons
Give the structural formula of Citronellol, L and D Carvone, Fenchol
Single bonds, double bonds, triple bonds resonating bonds, symmetry,
equivalence
Covalent, Polar covalent
To process the type/characteristics of a compound, determine/ask yourself
questions such as:
molecular shape--- long, stringy, pan shaped etc.
molecular formula--- one oxygen, two oxygen, no oxygen, nitrogen, etc.
functional group--- ester, carboxylic, amine, ether, alcohol, etc.
smell--- putrid is carboxylic, fishy is amine, etc.
Electron domains
Receptor sites: what they do, size, shape, polarity
Tetrahedral, Pyramidal, Trigonal Planar, Bent, Linear, Point
Smells come from gases. What substances provide gases, Do not be fooled,
solid substances such as D-carvone smells like caraway seeds (caraway seeds
are solid), like rye bread and L-carvone is minty. Also liquids that are highly
volatile have smell
Polarity (nonpolar or polar) intermolecular force partial charges
Number of carbons, numbers of hydrogens, long, stringy, frying pan, ball shaped
5-19 carbons long and stringy is sweet smelling, including fruity, floral smells
5 or less carbon alcohols are medicinal, 6 carbon chains that are flat are minty smell
6 carbon chains and ball shaped have camphor smell
More than one carbon chain and one oxygen ball shaped is camphor smelling.
Ethyl butyrate which is an acid and a liquid, smells like pineapple. You have
other examples on your flashcards.

Some diatomic elements that are small nonpolar gases, have a smell. So realize
there are not solid rules or characteristics to go by.
Water is polar and like most polar substances is an exception by not having a
smell. Could this be why receptor sites dissolve in moisture to work?
For Unit 1:
Know all lab equipment and how to safely use.
Know the safety rules. Review the Lab Safety Contract. Review notes of the
material and placement of the safety material in the lab area.
Know/recommend compound types from last semester and examples. (Ionic,
Molecular Covalent, Metallic, and Network Covalent.
