Isomers are compounds of the same molecular formula but different molecular structures. There are four important types of isomers. Structural isomers atoms are bound in different orders while stereoisomers are bound in the same order but oriented differently. Geometric isomers involve different arrangement about a double bond.

WebAug 13, 2024 · Optical isomers differ in the placement of substituted groups around one or more atoms of the molecule.

In general, there's no reason why a simple substituted biphenyl is flat either. The key is that if the barrier to rotation is low enough, then the different stereoisomers can interconvert, so you end up with a racemic mixture. For more substituted biphenyls, strain present in the planar form is high enough that it impedes free rotation ...
