(a)

Interpretation Introduction

Interpretation:

From the given alkyl halides undergoes E2 reaction has to be identified.

Concept Introduction:

An E2 reaction is a concerted, one-step reaction in which the proton and the halide ion are removed in the same step.

A strong base favours an E2 reaction.  A high concentration of a base favours an E2 reaction.  If one of the reactants is charged, an E2 reaction will be favoured by the least polar solvent that will dissolve the reactant.  If neither of the reactant is charged an E2 reaction is favoured by the protic polar solvent.  The major product is a stable alkene, unless the reactants are sterically hindered.
