U14A1 / understanding the structures, reactions and properties of functional group compounds.Moreen Mero
P1. Explaining the reactions of a range of carbonyl and non-carbonyl functional group compounds.
1. Halogenoalkane reactions:
- Substitution with hydroxide ion : reflux is been used to (1-bromopropane ) using heat and
solvent. which contains 50% water and 50% ethanol to make a reaction of nucleophilic
substitution.
- Substitution with ammonia NH3 : this is because gas is been involved in this reaction, therefore
beaker is not used but instead it is been done in a covered or a sealed container so that anything
would not get lost to the surroundings.

- Substitution with primary amine RNH2 : this reaction when it gets heated using ammonia
solution (concentrated) in ethanol, and also it is made using sealed container, or tube.
- Elimination with hydroxide ion : reflux is used using concentrated sodium hydroxide as well
as ethanol, with a solvent so it can speed up the reaction.

- Polymerisation manufacture of PVC : the solvent use in this reaction is excess chloroethane:
and using catalyst as well of Iron III chloride, so it can line the alkenes up. A constant
temperature must be kept between 320-340K when the reaction occurs, and the pressure must
be about 405300 Pa.
2. Alcohol reactions :
- Reaction with sodium metal: during this reaction a temperature of 25 degrees must be kept
which followed by the standard conditions.
