WebOnly chiral biphenyls are optically active. All chiral compounds are optically active. Optical activity can be determined experimentally using polarimeter tube which measures the specific rotation of light passing through the device. Alternatively the structure of the molecule can be used to determine whether the molecule is chiral. WebSolution. The correct option is B. The biphenyl compounds having a proper substitution at the ortho-position of benzene rings resulting in steric hindrance. This steric …

WebThe most important class of atropisomers are biaryls such as diphenic acid, which is a derivative of biphenyl with a complete set of ortho substituents. Heteroaromatic analogues of the biphenyl compounds also exist, where hindered rotation occurs about a carbon-nitrogen or a nitrogen-nitrogen bond.
