Neopentyl bromide, undergoes dehydrohalogenation to give alkenes even though it has no β − H . This is due to

Step-by-step solution

Neopentyl bromide give a carbocation as intermediate which undergo for rearrangement and show E 1 mechanism (even though it has no β − H atom). Thus Rearrangement of carbocations by E 1 mechanism is the correct option.
