Question

Draw three isomers of trans-1, 2-dichlorocyclobutane, and label them as either constitutional isomers or stereoisomers.

Short answer

The three isomers oftrans-1, 2-dichlorocyclobutane are as follow;

Step-by-step solution

Isomers and their types

Isomers are the molecules with same molecular formula but differ in the arrangement of atoms in space.

Depending upon the connectivity isomers are classified into two types;

1. Stereoisomers
2. Constitutional isomers

Stereoisomers are the isomers that have the same connectivity but difference in the spatial arrangement of atoms in space.

There are two types of stereoisomers enantiomers and diastereomers. Enantiomers are the stereoisomers that are the mirror images of each other while diastereomers are not mirrored images of each other.

Constitutional isomers are the isomers that have differences in connectivity.

There are three types of constitutional isomers, positional isomers, chain isomers, functional isomers.
