Why do we get isopropyl benzene on treating benzene with 1-chloropropane instead of n-propyl benzene?

Options

  1. AThe reaction is selective for the formation of isopropyl benzene.
  2. BIsopropyl chloride is more reactive than n-propyl chloride.
  3. CSteric hindrance favors the formation of isopropyl benzene.
  4. DThermodynamic stability leads to the formation of isopropyl benzene.

Correct answer

C. Steric hindrance favors the formation of isopropyl benzene.

Step-by-step solution

The formation of isopropyl benzene is favored due to steric hindrance. The isopropyl group is smaller and less bulky than the n-propyl group, allowing for easier electrophilic substitution on the benzene ring.
