Question

The Friedel-Craft's reaction of n-propyl chloride with benzene in the presence of anhydrous $AlC{l}_3$ gives:

• A. n-propyl benzene
• B. Isopropyl benzene
• C. 1,4-dipropyl benzene
• D. 1,2-dipropyl benzene

Answer 1

The correct option is B Isopropyl benzene

The $1^{\circ }$ carbonium ion isomerizes to the more stable $2^{\circ }$ carbonium ion, which in turn reacts with benzene to give isopropyl benzene.
