Stereoisomers and Isomerism

Flashcards covering key concepts related to stereoisomers, isomerism types, and their properties.

Stereoisomers

Molecules with the same molecular formula but different spatial arrangements.

E-Z Isomerism

Stereoisomerism where groups are on the same (Z) or opposite (E) sides of a double bond.

E isomer

Isomer with highest priority groups on opposite sides of a double bond.

Z isomer

Isomer with highest priority groups on the same side of a double bond.

Cahn-Ingold-Prelog (CIP) Rules

Rules for assigning priority to groups based on atomic number at a double bond or chiral center.

Chiral centre

A carbon atom bonded to four different groups.

Optical isomers

Isomers that are non-superimposable mirror images.

Enantiomers

Two optical isomers that are mirror images of each other.

Optical activity

The capacity of optical isomers to rotate plane-polarized light.

Racemic mixture

A 1:1 mixture of enantiomers, resulting in no net optical
