(a)

Interpretation Introduction

Interpretation:

The different alkene products formed from the given substrate when treated with a strong base are needed to be find out.

Concept Introduction:

Elimination Reaction: It is just reverse reaction of addition where substituent from the given molecule is removed via $E1$ (the reaction depends only on the substrate involved in the reaction) or $E2$ (the reaction depends on both of the substituents in the reaction) mechanism.

Regiochemical reaction: Alkenes are formed when alkyl halides are treated with bases via $\beta$-elimination reaction. In $\beta$-elimination reaction, elimination of one proton and one halo group is taking place.

The product of the elimination reaction is depends upon the two $\beta$-elimination of alkyl halide. If the $\beta$-positions are identical and the products formed are also identical. If the β-positions are different and the products formed are also different. This means the double bond can form in two different regions so this type of reaction is called regio-selective and the products are called as regiochemical outcomes.
