Vedclass · Answer

(D) An elimination reaction involves the removal of atoms or groups from adjacent carbon atoms to form a $\pi$-bond (double or triple bond).In reaction $(a)$,cyclohexanol undergoes dehydration in the presence of $H_2SO_4$ to form cyclohexene,which is an elimination reaction.In reaction $(b)$,trans$-1,2-$dibromocyclohexane reacts with $KI$ to undergo debromination,forming cyclohexene,which is also an elimination reaction.Reaction $(c)$ is a substitution reaction where the methoxy group replaces the bromine atom.Therefore,both $(a)$ and $(b)$ are elimination reactions.
