Presence of chiral center is not an essential condition to show optical isomerism. Essential condition is, compound should show non-superimposable mirror image. Allenes do not contain chiral center but show optical isomerism when different groups are attached on double bonded carbonds. Biphenyls alos show optical isomerism when both rings are perpendicular to each other and any ring should not contain plane of symmetry. Which of the following biphenyl compounds is optically active?

An organic compound having a carbon attached to four different group is optically actve, But is it that opposite is also true? That is, do all optically active organic compounds have chiral carbons? Not necessarily. Presence or absence of chiral centre is not the sufficiet criterion for optical activity. The ultimate criterion is presence or abosence of either plane or centre of symmtry. Two compounds which are non super im[osabble mirror images of each other are called enantiomers. If a compound contains more than one chiral carbon, new words are required to describe the relationship between various stereo isomers of the compounds. Those words are diastereomers and mesomers. Which of the following statements is/are correct regarding the above compound.
