(a)

Interpretation Introduction

To determine: The dehydrohalogenation product that results if the given alkyl halide is heated in alcoholic $\text{KOH}$ and the major and minor products if more than one product is formed by this reaction.

Interpretation: The dehydrohalogenation product that results if the given alkyl halide is heated in alcoholic $\text{KOH}$ and the major and minor products if more than one product is formed by this reaction are to be predicted.

Concept introduction: The chemical reaction that consists of an alkyl halide, a good leaving group that reacts with Lewis base to form an alkene is termed as elimination reaction. In this reaction there is complete removal of the leaving group without any substitution.

The bimolecular elimination reaction that favours the removal of an HX substituent from an alkyl halide that needs a base to remove $\text{H}$ from carbon adjacent to the leaving group that in turn forms a double bond is termed E2 elimination reaction.

The elimination of hydrogen halide molecule is termed as dehydrohalogenation. This type of reaction has an unfavourable enthalpy change but a favourable entropy change.
