Chapter 3, Problem 23P

Interpretation Introduction

Interpretation:

Structural formulas for all the bicyclic isomers of ${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}$ and ${\text{C}}_{\text{6}}{\text{H}}_{\text{10}}$, excluding compounds that contain methyl or ethyl groups, are to be written.

Concept introduction:

Bicyclic compounds contain two rings. The two rings may share two adjacent carbon atoms.

The two rings may have only one carbon atom in common. These are called as spiro compounds. The bridged bicyclic compounds contains two common atoms to two or more rings.
