What are geometrical isomers? Explain, structurally, why geometrical isomers exist.
Molecules differing in the relative bond positions of two groups about carbon-carbon double bonds. Free rotation is not possible about a carbon-carbon double bond. Thus, groups attached to the double-bonded carbons can orientate themselves so that they are either on the same side of the molecule (cis) or on opposite sides (trans).
