Stereoisomerism in biphenyl compounds, condition for biphenyl compounds to exhibit optical activity(1)

by

Stereoisomerism in biphenyl compounds Biphenyl is an aromatic hydrocarbon with a molecular formula (C6H5)2, consists of two connected phenyl ring. Due to lack of formation of groups, it is unreactive in nature. (The two phenyl groups are linked by a single bond sp2 known as pivotal bond). Biphenyl does not show geometrical isomerism, its show … Read more

Conformational isomerism – ethane, n-butane, cyclohexane, energy diagram & conformers, with best notes

by

Conformational isomerism These are different spatial arrangement of a molecules that are generated by rotation about single bond. If two different 3D arrangement in space of the atoms in a molecule are inter convertible merely by kee rotation about bonds, they are called conformation. The difference between conformational isomers & configurational isomers is that configuration … Read more
