Chapter FRP, Problem 33P

Interpretation Introduction

Interpretation:

The reaction yielding $trans\text{-}2\text{-butene}$ and $cis\text{-}2\text{-butene-}2\text{-}d$ is to be explained.

Concept Introduction:

Elimination reactions are the reactions in which two substituents are removed from a molecule, in a one or two step mechanism.

A base removes hydrogen atom from $\beta$ carbon, followed by removal of halogen atoms or any good leaving group from $\alpha$ carbon, resulting in the double bond ($\pi$) formation.
