In the following reaction ‘ X ’ is CH 3 CH 2 4 CH 3 → HCl △ Anhy . AlCl 3 X major product

Options

  1. ACH 3 CH 2 4 CH 2 Cl
  2. BCl - CH 2 - CH 2 4 - CH 2 - Cl

Correct answer

B. Cl - CH 2 - CH 2 4 - CH 2 - Cl

Step-by-step solution

When n-Hexane is heated with anhydrous AlCl 3 and HCl gas at 573 K under a pressure of about 30 - 35 atm it Isomerises to give a branched chain alkanes. CH 3 CH 2 4 CH 3 → HCl △ Anhy . AlCl 3 CH 3 2 CHCH 2 CH 2 CH 3 2 - methylpentane + 3 - methylpentane Major product in the above reaction is 2-methylpentane.
