WebIn previous post, we mentioned that enantiomers (also known as optical isomers) rotate plane-polarised light in opposite directions and are said to exhibit optical activity.So how do we know if an organic molecule rotate … WebNov 20, 2024 · Which biphenyl is optically active? I know that it can never be 1. I don't think it will be 4 either as I read that it should be ortho -substituted biphenyl. So, when I look at 2 and 3, I can't make out which one should be the correct answer. Should it always be two ortho substituents on each phenyl group for it to be optically active?
