Geometric isomerism, also known as cis-trans isomerism, arises due to restricted rotation, typically around a double bond or in cyclic compounds. The isomers differ based on the relative positions of substituents. For instance, in 2-butene, the cis isomer has both methyl groups on the same side of the double bond, while the trans isomer has them on opposite sides. On the other hand, optical isomerism occurs in molecules with chiral centres, leading to non-superimposable mirror images called enantiomers. For example, lactic acid exists as two enantiomers: D-lactic acid and L-lactic acid, which rotate plane-polarised light in opposite directions.
