Ait is second order and bimolecular.
BIt is first order and unimolecular.
Cit is first order and bimolecular.
DIt is second order and unimolecular.
Correct Answer

Solution

The given reaction (dehydrochlorination of 2-chlorobutane in presence of alcoholic KOH to form 2-butene) proceeds via $$ E_1cB$$ mechanism .
$$E_1$$= unimolecular elimination ;cB = conjugate base.
It is second order and unimolecular.
