Chapter 17, Problem 17.80EP

(a)

Interpretation Introduction

Interpretation:

The rings in pyrrole is saturated, unsaturated or fused has to be indicated with the help of figure 17-8.

Concept Introduction:

Amines are a class of organic compounds that contain amino functional group.  Heterocyclic amine is also a class of organic compound in which the nitrogen atom of the amine group is present in the aromatic or nonaromatic ring.

Saturated ring in organic chemistry means there are no double bonds present between two carbon atoms in the compound that is under consideration.

Unsaturated ring in organic chemistry means that there has to be at least one double bond or triple bond present in the compound that is under consideration.

Fused ring in organic chemistry means that there has to be at least two cyclic rings that share at least two common atoms between then.
