isnt the answer e)none of theses
since the correct : Structural Isomers
Optical isomers are the compounds which has the same number of atoms and bonds, but different type of spatial arrangement of bonds. The compounds as these isomers are non-superimposable mirror images of each other.
Structural isomers are the constitutional isomers in which two compounds has same molecular formula but different structures.
Stereoisomer are the compounds which have same number of atoms and bonds but differs by their spatial arrangement of atoms . Optical isomers are a type of stereo isomers.
Geometric isomers are the isomers which has same number of atoms and even same structural formula but these compounds differ in the arrangement of bonds. For example :…
