Predict the order of reactivity of the following compounds in S N 2 reaction: The four isomeric bromobutanes

Options

  1. ACH 3 CH 2 CH 2 CH 2 Br > (CH 3 ) 2 CHCH 2 Br > (CH 3 ) 3 CBr > CH 3 CH 2 CH(Br)CH 3
  2. B(CH 3 ) 2 CHCH 2 Br > CH 3 CH 2 CH(Br)CH 3 > (CH 3 ) 3 CBr > CH 3 CH 2 CH 2 CH 2 Br
  3. CCH 3 CH 2 CH 2 CH 2 Br > CH 3 CH 2 CH(Br)CH 3 > (CH 3 ) 3 CBr > (CH 3 ) 2 CHCH 2 Br
  4. DCH 3 CH 2 CH 2 CH 2 Br > (CH 3 ) 2 CHCH 2 Br > CH 3 CH 2 CH(Br)CH 3 > (CH 3 ) 3 CBr

Correct answer

D. CH 3 CH 2 CH 2 CH 2 Br > (CH 3 ) 2 CHCH 2 Br > CH 3 CH 2 CH(Br)CH 3 > (CH 3 ) 3 CBr

Step-by-step solution

Correct Option is : (D) CH 3 CH 2 CH 2 CH 2 Br > (CH 3 ) 2 CHCH 2 Br > CH 3 CH 2 CH(Br)CH 3 > (CH 3 ) 3 CBr
