(a)

Interpretation Introduction

Interpretation:

The rings that are aromatic among the given bases are to be stated.

Concept introduction:

The conditions that a molecule must follow to be an aromatic are shown below.

  • The given compound must be cyclic in nature.
  • It must be planar.
  • There must be no sp3 hybridized carbon in the given compound.
  • The compound must follow Huckel’s rule of aromaticity that is (4n+2)π electron system must be present.

If the given compound follows first three conditions but it follows 4nπ electron system, then it is antiaromatic in nature. If the given compound fails to follow any of the above conditions then it is non-aromatic in nature.

(b)

Interpretation Introduction

Interpretation:

Nitrogen atoms that are basic in nature in the given bases are to be stated.

Concept introduction:

According to Lewis concept, the species that can easily accept the electrons is known as an acid and the species that donates the electrons is known as a base.

(c)

Interpretation Introduction

Interpretation:

The possibility of the formation of aromatic tautomers by the given bases is to be predicted.

Concept introduction:

The constitutional isomers that involve the relocation of protons and are interconvertible into each other are known as tautomers.
