Detailed explanation-1: -Thus there are two requirements for cis-trans isomerism: Rotation must be restricted in the molecule. There must be two nonidentical groups on each doubly bonded carbon atom.
Detailed explanation-2: -Conditions for geometrical isomerism: A compound will show geometrical isomerism if it fulfils the following two conditions: There should be restricted (frozen) rotation about a bond in the molecule. Both substituents on each carbon about which rotation is frozen (restricted) should be different.
Detailed explanation-3: -Cis isomers are molecules with the same connectivity of atoms. They feature same side groups placed on the same side of a double bond. Trans isomers feature molecules with same side groups placed on opposite sides of a double bond.
