Chapter 11, Problem 11A.5BST

Interpretation Introduction

Interpretation:

The cis and trans isomers of $\text{1,2-dimethylcyclohexane}$ has to be identified.

Concept Introduction:

Stereoisomers:  Stereoisomers have the same connectivity but difference in the spatial arrangement of atoms.

Geometrical isomers:  In geometrical isomers, atoms have different arrangements on either side of a double bond above or below the ring of a cycloalkane or cycloalkane.  If the atoms are present on the same side of the double bond, then it is cis-isomer and if they are present on the opposite side of the double bond, then it is trans-isomer.
