Chapter 11.SE, Problem 24VC

Interpretation Introduction

Interpretation:

The structure of the compound has to be drawn, and Z or E stereochemistry has to be assigned to the product which is underwent E₂ reaction with NaOH.

Concept introduction:

Z or E stereochemistry:

The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as Z-isomer (or cis isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as E-isomer (or trans isomer).

Example:

E₂ elimination:

Alkyl halide forms an alkene from the abstraction of the proton from the β-carbon atom followed by elimination of the bromine in a single step.

Given information:

The molecule is given in Ball-and-stick model and it undergoes E₂ elimination with NaOH.
