a.

Interpretation Introduction

Interpretation:

The compound ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CONHCH}}_{\text{2}}{\text{CH}}_{\text{3}}$ has to be drawn and the compound has to be labelled as carboxylic acid, ester, or amide.

Concept Introduction:

Functional group is an atom or a group of atoms that is present in a compound which is responsible for the physical and chemical properties of the compound.  Carbonyl carbon bonded to a hydroxyl group is known as carboxylic acid.  Carbonyl carbon bonded to an alkoxy is known as ester.  Carbonyl carbon bonded to a nitrogen atom is known as amide.  If nitrogen atom is bonded to other carbon atoms only means it is an amine.

b.

Interpretation Introduction

Interpretation:

The compound ${{\text{(CH}}_{\text{3}}\text{)}}_{\text{3}}\text{N}$ has to be drawn and the compound has to be labelled as carboxylic acid, ester, or amide.
