WebApr 14, 2024 · It is an essential concept in organic chemistry and plays a crucial role in drug design, materials science, and biochemistry. This article will provide an overview of stereochemistry, including its definition, types, chirality, enantiomers, diastereomers, and stereoisomerism. Definition of Stereochemistry: WebNov 20, 2024 · Sorted by: 11. Biphenyl 2 is the only optically active compound here. These stereoisomers are due to the hindered rotation about the 1,1'-single bond of the compound (Ref.1). Biphenyl 3 is not optically active, because partially allowed rotation about the 1,1'-single bond of the compound (rotation is only partially restricted).
