WebThe geometrical isomerism arises when atoms or groups are arranged differently in space due to restricted rotation of a bond or bonds in a molecule. E.g. 1) Two different spatial arrangements of methyl groups about a double bond in 2-butene give rise to the following geometrical isomers. i.e., cis-2-butene and trans-2-butene. WebThe E-Z system of nomenclature is illustrated below. That isomer which has the two highest ranking groups, based on sequence rules, on the same side of the double bond is called (Z) and other isomer is designated (E). Live example. A typical example of a drug molecule that exhibits geometrical isomerism is the antihistaminic agent triprolidine.
