Question

Why a molecule show restriction in rotation around bonds?

Answer 1

Introduction. As a consequence of the double bond, some alkene compounds exhibit a unique type of isomerism. Rotation around a single bond occurs readily, while rotation around a double bondis restricted. The pi bond prevents rotationbecause of the electron overlap both above and below the plane of the atoms.
