Those stereoisomers are called configurational isomers if they differ in spatial arrangement of atom or group and are not interconvertible without cleaving a bond. Geometrical isomer arises due to restricted rotation about a bond or centre. The number of G.I is 2^(n) where n= number of stereoisomers, in some cases the number of G.I is less than 2^(n) in case where either side nomenclature will be possible. Which of the following compounds can show geometrical isomerism.
