Question

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

Short answer

Answer

All the stereoisomers are shown hereunder.

Step-by-step solution

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.

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.
