Predict the order of reactivity of the following compounds in S N 1 reaction: C 6 H 5 CH 2 Br, C 6 H 5 CH(C 6 H 5 )Br, C 6 H 5 CH(CH 3 )Br, C 6 H 5 C(CH 3 )(C 6 H 5 )Br

Options

  1. AC 6 H 5 C(CH 3 )(C 6 H 5 )Br > C 6 H 5 CH(C 6 H 5 )Br > C 6 H 5 CH 2 Br > C 6 H 5 CH(CH 3 )Br
  2. BC 6 H 5 C(CH 3 )(C 6 H 5 )Br > C 6 H 5 CH(C 6 H 5 )Br > C 6 H 5 CH(CH 3 )Br > C 6 H 5 CH 2 Br
  3. CC 6 H 5 CH(CH 3 )Br > C 6 H 5 CH 2 Br > C 6 H 5 C(CH 3 )(C 6 H 5 )Br > C 6 H 5 CH(C 6 H 5 )Br
  4. DC 6 H 5 CH(C 6 H 5 )Br > C 6 H 5 CH(CH 3 )Br > C 6 H 5 CH 2 Br > C 6 H 5 C(CH 3 )(C 6 H 5 )Br

Correct answer

B. C 6 H 5 C(CH 3 )(C 6 H 5 )Br > C 6 H 5 CH(C 6 H 5 )Br > C 6 H 5 CH(CH 3 )Br > C 6 H 5 CH 2 Br

Step-by-step solution

Correct Option is : (B) C 6 H 5 C(CH 3 )(C 6 H 5 )Br > C 6 H 5 CH(C 6 H 5 )Br > C 6 H 5 CH(CH 3 )Br > C 6 H 5 CH 2 Br
