Question

The decreasing order of reactivity towards dehydrohalogenation $(E_1)$ reaction of the following compounds is :

• A. B > A > D > C
• B. B > D > C > A
• C. B > D > A > C
• D. D > B > C > A

Answer 1

Answer: (D)

Reactivity $D>B>C>A$
Carbocation formed from $D$ is most stable Carbocation formed from $A$ is least stable
