(a) Interpretation: Interpret the possible reaction of propyne with given reagents. Concept introduction: Propyne is an unsaturated hydrocarbon with three carbon atoms in the parent chain and one triple bond between two carbon atoms. Because of the presence of multiple bonds in the molecule, alkynes tend to give addition reactions such as hydrogenation (addition of H 2 ), bromination (addition of Br 2 ), hydration (addition of H 2 O) etc.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .

Interpretation Introduction

(a)

Interpretation:

Interpret the possible reaction of propyne with given reagents.

Concept introduction:

Propyne is an unsaturated hydrocarbon with three carbon atoms in the parent chain and one triple bond between two carbon atoms. Because of the presence of multiple bonds in the molecule, alkynes tend to give addition reactions such as hydrogenation (addition of H₂), bromination (addition of Br₂), hydration (addition of H₂O) etc.

Interpretation Introduction

(b)

Interpretation:

Interpret the possible reaction of 4-hydroxy-2-butanone with given reagents.

Concept introduction:

4-hydroxy-2-butanone is a hydroxyl ketone. It has two functional groups; keto group and hydroxyl group. The hydroxy or alcoholic group can show dehydration reaction when it is heated with concentrated sulfuric acid. It results the formation of ether as the final product.

Interpretation Introduction

(c)

Interpretation:

Interpret the possible reaction of benzoic acid with given reagents.

Concept introduction:

Benzoic acid is an aromatic carboxylic acid with −COOH group directly bonded with benzene ring. Since it is an aromatic compound so addition reactions are not possible due to extra stability of aromatic ring. Benzoic acid mainly exhibits the reactions of carboxylic acid with base and alcohol to form ester.
