How does geometric isomerism arise

WebNov 30, 2024 · Geometric isomerism or configurational isomerism is found in the molecules having the restricted rotation about the double bond.Another term for geometrical isomers is “cis-trans “isomers. The prefixes “cis” and “trans” are from Latin origin, where cis means “this side of” and trans means “the other side of”. i. WebHow does geometric isomerism arise? Same molecular formula, same connectivity but different spatial arrangement of atoms. Geometric isomerism arises because of restricted rotation around carbon- carbon double bonds. What is the difference between a "cis-" and a "trans-" stereoisomer? Cis- identical atom is on the same side of the molecule
