Interpretation:
Compound cis-
Concept introduction:
A carbon atom that has four nonequivalent atoms or groups attached to it is known as the chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers. A carbon atom that does not have four nonequivalent atoms or groups attached to it is known as an achiral carbon atom.
(b)
Interpretation:
Compound trans -
