Question

How many total isomers for the complex [co(en)2cl2]+?

Answer 1

How many isomers are possible for dimethyl cyclohexane?

As we required total number of isomers (i.e. positional +stereo), so lets first look at all positional isomers and then we will check its number of stereisomers.

Possible positional isomers for dimethyl cyclohexane-

1,1 dimethyl cyclohexane

1,2 dimethyl cyclohexane

1,3 dimethyl cyclohexane

1,4 dimethyl cyclohexane

Now let's check their number of stereoisomers respectively-

0

3

3

3

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