a.

Interpretation Introduction

Interpretation:

The compound ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{)}}_{\text{3}}\text{N}$ is water soluble or water insoluble has to be labelled.

Concept Introduction:

Amines are basic in nature.  Primary amines and secondary amines can involve in hydrogen bonding with water molecules.  Tertiary amines cannot form hydrogen bonding with water as there are no hydrogen atoms attached to the nitrogen atom.

Ammonium salts are similar to ionic compounds.  They have cation and anion.  Ammonium salts are highly soluble in water.
