The decreasing order of reactivity towards dehydrohalogenation ( E _ 1 ) reaction of the following compounds is:

Options

  1. AD>B>C>AD > B > C > A
  2. BB>D>A>CB > D > A > C
  3. CB>D>C>AB > D > C > A
  4. DB>A>D>CB > A > D > C

Correct answer

A. D>B>C>AD > B > C > A

Step-by-step solution

E1 reaction proceeds via carbocation formation, therefore greater the stability of carbocation, faster the E1 reaction.
