Why do we get isopropyl benzene on treating benzene with 1-chloropropane instead of n-propyl benzene?
Options
- AThe reaction is selective for the formation of isopropyl benzene.
- BIsopropyl chloride is more reactive than n-propyl chloride.
- CSteric hindrance favors the formation of isopropyl benzene.
- 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.
