why does conformation arise in alkanes,while some alkenes undergo geomertical isomerism ?
Asked by ruchira121996 | 26 Mar, 2013, 07:33: PM
Expert Answer
Geometrical isomerism is possible for those compounds in which free rotation about bond is not possible in alkenes a double bond restrict the free rotation so arrangement of substituents on double bounded carbon may occur in two ways, same groups at same side of the plane of double bond (Cis) or at opposite side (Trans).
