Chapter 3.13, Problem 36P

(a)

Interpretation Introduction

Interpretation:

Given substituted axial and equatorial cyclohexane molecule, whether cis isomer or a trans isomer has to be identified.

Concept introduction:

Stereoisomerism (or) geometric isomerism:

It is known as cis-trans isomerism or E-Z isomerism is a form of stereoisomerism the each of two or more chemical compounds having the same molecular formula but a different geometric arrangement; an unsaturated compound or ring compound in which rotation around a carbon bond is restricted, as in (cis) and (trans) configurations know as geometric isomerism.

For example the cyclohexane ring has two substituent’s, must take both substituents into account when predicting which of the two chair conformers is more stable, like 1,4-dimethylcyclohexane has presence two methyl groups in 1,4-positions.

Conformers:

The different spatial arrangements of the atoms the result from rotation about a single bond is called conformational isomers.
