Group 2: CARBOHYDRATES - Composed of carbon chains where one or more carbons has been oxidized. These
oxygen atoms (and nitrogen atoms) make the carbon based molecule behave
differently the functional groups. Molecules that have the same groups of
Oxygens/Nitrogens all tend to behave similarly.

Reactions involving organic molecules
This section deals with the variety of chemical reactions that involve the organic molecules you have just learn to identify
1) They all combust- forming oxides ie C4H10 + 6.5 O2 → 4 CO2 + 5 H2O
or H2NC5H10COOH + 9¼ O2 → 6 CO2 + 6½ H2O + NO2
15.a) 3-ethyl-2-methylheptane + O2 (g)
b) 2,5-diammino-4-isopropylhexanoic + O2 (g)
a) C10H22 + 15.5 O2 → 10 CO2 + 11 H2O
b) (NH2)2C8H15COOH

15 O2 → 9 CO2 + 10 H2O + 2 NO2
2) The alkANEs (fully saturated) tend to undergo SUBSTITUTION reactions producing an alkyl halide ie
halogenation with Cl2 or Br2 etc (see pg 24 CHEM 12)

**NOTE: Stability of the carbonyl free radicals is 3° > 2° > 1° . this means that if propane undergoes this
type of reaction the only product formed would be 2-chloropropane.

3) The alkyl halides can undergo an elimination reaction forming an alkene (see pg 36 - CHEM 12)
CH3– CHCl – CH3 + OH- (a base) → CH2=CH– CH3 + H2O + Cl-
4) The alkENEs & alkYNEs (unsaturated) are much more reactive because of the π cloud of electrons on top of the
double bond and tend to undergo ADDITION reactions across this dble bond. (see pg 25 CHEM 12)
C3H6 + Br2 → C3H6Br2 halogenation
C3H6 + H2 → C3H8
hydrogenation
C3H6 + HCl → C3H7Cl hydrohalogenation

*This MECHANISM is“ELECTROPHYLLIC” (hungry for electrons) – ΔG is very negative

**NOTE: Stability of the carbonium ion C+ is 3° > 2° > 1° . this means that if 1-propene undergoes this
type of reaction with a hydrogen halide like HCl the only product formed would be 2-chloropropane as
the 2° carbon(in the middle) would become C+ and that is where the negative Cl- will attach. This is
known as Markovnikov’s Rule (the H attaches to the carbon that already has the most H’s)
CH2=CH–CH3 + HCl → CH3– CHCl – CH3
