Question

How many structural and geometrical isomers are possible for dimethylcyclohexane?

Answer 1

Possible positional isomers for dimethyl cyclohexane-

1,1 dimethyl cyclohexane

1,2 dimethyl cyclohexane

1,3 dimethyl cyclohexane

1,4 dimethyl cyclohexane
.

check their number of stereoisomers respectively-

0

3

3

3

So total number of isomers= 1+3+3+3=10
