Chapter 23, Problem 23.16QP

Interpretation Introduction

Interpretation:

From the given set of compounds, the compound which could exist as cis-trans isomer has to be found out.

Concept Introduction:

Geometric isomers are the isomers of same compound which differ in the relative positions the atoms occupy in space.  For alkene geometric isomers are possible if the carbon atoms in the end of the double bond are not bonded to same groups or atoms.  Usually trans isomer is more stable than cis isomer as the steric hindrance will be very less.

To identify: The compound which can exist as cis-trans isomer.
