The compound above exhibits
Geometric isomerism
Positional isomerism
Structural isomerism
Optical isomerism
Correct answer is D
Optical isomers are molecules that are non-superimposable mirror images of each other and they are not identical. Molecules with a chiral carbon show this kind of isomerism. Chiral carbon, also known as asymmetric carbon, refers to carbon atom that are bonded to four different atoms or groups of atoms.
