Chapter 23, Problem 23.88QP

Interpretation Introduction

Interpretation:

The isomeric alkenes should be identified. Isomeric alkenes are stereoisomer or constitutional isomer should be identified.

Concept introduction:

Isomer: Molecule has same molecular formula but different structural arrangement is called isomer.

Chiral: Absence of a plane of symmetry or a center of symmetry is called chiral molecule, a non-superimposable on its mirror image is called chiral. A carbon atom is attached by the four different groups is called chiral carbon.

Constitutional isomer: (or structural) isomers differ in the connectivity they contain different functional groups and / or bonding patterns is called constitutional isomer.

Enantiomers: Two stereoisomers that are mirror images of each other and they are non-supposable.

Diastereomers: Two stereoisomers that are non-mirror images of each other and they are non-supposable
