Question

Neopentyl bromide undergoes dehydrohalogenation to give alkenes even though it has no $\beta$- hydrogen. This is due to

• A. E2 mechanism
• B. E1 mechanism
• C. Rearrangement of carbocations by E1 mechanism
• D. E1cB mechanism

Answer 1

Answer: (C)

Rearrangement of carbocations by E1 mechanism

Answer 2

Neopentyl bromide give a carbocation as intermediate which undergo for rearrangement and show $E_{1}$ mechanism (even has no $\beta- H$ atom $)$.
