Biphenyl optical activity
WebMay 1, 2024 · Biphenyls are an important intermediate in organic chemistry which constitutes the structural moiety of a wide range of compounds with profound pharmacological activity. Being a neutral molecule (due to absence of the active functional moiety on it), biphenyls are required to be functionalized i.e. introduction of active group … WebBiphenyl Systems show optical activity when the following conditions are satisfied: Each ring should have 2 different ortho substituting groups. In a left ring have 2 different ortho substituting groups while right ring has 2 same group thus it is optically inactive.
