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

The decreasing order of reactivity towards dehydrohalogenation E1 reaction of the following compounds is:
 
  1. D>B>C>A
  2. B>D>A>C
  3. B>D>C>A
  4. B>A>D>C

Solution

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