Question

What is the difference between optical isomerism and geometrical isomerism?

Answer 1

Optical isomerism	Geometrical isomerism
Optical isomerism is the type of stereoisomerism that have the same molecular formula and connectivity of atoms but different spatial arrangement.	Geometrical isomerism is also the type of stereoisomerism in which the same substituent is attached differently to the carbon-carbon double bond.
They posses the similar physical properties.	They possess different physical properties.
In optical isomers, they do not show cis and trans isomers.	In geometrical isomers, they show cis and trans isomerism.
Optical isomers are optically active in nature.	In geometrical isomer, only cis can show the optical activity while trans is optically inactive in nature.
