Question

Using skeletal structures, draw the stereoisomers of

a. 2,4-dichloroheptane. b. 2,4-dichloropentane.

Short answer

We have to draw the structures of stereoisomers of following compounds:

a)

b)

Step-by-step solution

Some definitions:

What is stereoisomer-

Two or more compounds which differ in the spatial arrangement of their atoms are called as stereoisomers i.e the molecules which are stereoisomers of each other are made from same atoms, connected in the same sequence but the atoms are arranged differently in space.

What is stereocentres:

An atom with three or more different attachments and interchanging of two of these attachments leads to another stereoisomer that C-center is called as stereocenter.

All asymmetric centres are stereocentres but all stereocentres can’t be asymmetric.

What is skeletal structure

In this series of atoms bonded together that form the essential structure of the compound. This skeleton can consist of chairs, branches and rings of bonded atoms.

This is skeletal structure of sec-butyl tert-butyl ether.
