Total number of isomers (including stereoisomers) obtain on monochlorination of methylcyclohexane is

Correct answer

12

Step-by-step solution

Compound A and B given above have no chiral centre and doesn't show geometrical isomerism. Compound C and D given above have two chiral centres each and each of them forms 4 optical isomers. And compound E has 2 E and Z isomers due to restricted rotation of groups. Hence, the total number of isomers will be 12.
