When n-hexane is heated with anhydrous `AICl_(3)` and HCl gas, the major product obtained is

A

1-chlorohexane

B

2-chlorohexane

C

3-chlorohexane

D

mixture of 2-methylpentane and 3-methylpentane

Text Solution

Verified by Experts

The correct Answer is:
D
When n-hexane is heated with anhydrous `AlCl _(3)` and HCl gas, at 573 under a presure of about `30-35` atmosphere, it isomerises to give a mixture of branched chain alkanes.
