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?

WebJan 10, 2024 · 1 "optical activity" is a problematic term if only because it implies EM radiation in the visible range. Unfortunately there isn't a simple general term. Though you could say, "can chiral macroscopic objects rotate the plane of EM waves of a suitable wavelength?" – matt_black Jan 12, 2024 at 13:59 Add a comment 2 Answers Sorted by: 2 WebUsing a technique called polarimetry, optical activity is measured by a device called a polarimeter. Monochromatic light (light containing a single color) is filtered through a polarizer to produce plane-polarized light, and it is passed through the sample.
