Chapter 25, Problem 84AP

Interpretation Introduction

Interpretation:

The representation of constitutional isomers, $cis/trans$ stereoisomers, enantiomers, resonance, and different representations of the same structure are to be identified.

Concept introduction:

cis-trans Isomers are an organic molecule that have double bonds. The attachment of two similar groups to the carbon on the same side is called cis-isomer, and if the attachment is on the different side, it is called trans-isomer.

When isomeric molecules have the same molecular formula but differ in bonding patterns and atomic organization, they are known as constitutional isomers.

Enantiomers are one of the two molecules that are a mirror image of each other and are non-superimposable.

In resonance structures, the electrons can move in order to help stabilize the molecule and should have the same number of electrons.
