Chapter 10: Q.20. (page 404)

Question: Draw all stereoisomers formed when 1,2-dimethylcyclohexene is treated with HCl. Label pairs of enantiomers.

Short Answer

Expert verified

Answer

All the stereoisomers are shown hereunder.

Step by step solution

01

Electrophilic addition of H+

The pi-electron density attacks the acidic hydrogen from the HX molecule, leading to the cleavage of pi-bond and the formation of a carbocation.

02

Enantiomers and diastereomers

Enantiomers are mirror images of a compound that are not superimposable on each other.

Diastereomers are not mirror images of any compound.

03

Products of the given reactions

The reactions of all the stereoisomers of 1,2-dimethylcyclohexene with HCl are shown hereunder.
