Organic chemistry Quiz 10: Hydrocarbons derivatives and alcohols

#1. (14) The only alkene which gives primary alcohol by catalytic hydration.

a)Ethene

b)ethyne

c)propene

d) a and c

#2. (1) (-COOH) group is named carboxylic group.

a)Because it is composed of carbonyl group and hydroxyl group

c)because it is composed of carboxyl group and hydroxyl group

c) because it is composed of carbon monoxide and hydroxyl group

d) no correct answer

#3. (2) Alcohols are considered as derivatives of both water and alkanes

a)Because alcohols are derived from water by replacing one hydrogen atom by an alkyl or aryl group while the are derived from alkanes by replacing hydrogen atom or more by one or more hydroxyl group

b)because alcohols are derived from water by replacing one oxygen atom by an alkyl or aryl group while the are derived from alkanes by replacing hydrogen atom or more by one or more hydroxyl group

c) because alcohols are derived from water by replacing one hydrogen atom by hydroxyl group or aryl group while the are derived from alkanes by replacing hydrogen atom or more by one or more hydroxyl group

d) because alcohols are derived from water by replacing 2 hydrogen atom by an alkyl or aryl group while the are derived from alkanes by replacing hydrogen atom or more by one or more hydroxyl group
