Chapter 2, Problem 9PP

Interpretation Introduction

Interpretation:

For the given molecular formula, the structural formula for all the alkenes are to be written. In each case, the compounds that are cis-trans isomers of each other are to be designated and for each, the dipole moment is to be predicted.

Concept Introduction:

Cis-trans isomerism arises by restricted rotation of groups that are joined together by double bonds.

Like all other isomers, the cis-trans isomers also have the same molecular formula, but different structural formula.

If the molecule has dipole moment, it is termed as polar molecule. The symmetrical molecules are non-polar because the dipole moment cancels each other
