Optical activity in chemistry
WebApr 9, 2024 · Optical activity is a phenomenon that describes the ability of rotation, thus optical activity is also known as optical rotation. Optical activity is different from … WebUsually, we look at a Fischer projection so one of the vertical bonds to a chiral carbon is in the plane of the paper. Then, the vertical bonds above and below that bond are behind the plane of the paper. When we move to a different chiral carbon we may choose to view the molecule eo a different bond is in the plane of the paper. Comment ( 5 votes)

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? grand river racetrackWebFeb 17, 2024 · I understood the simplified reason for optical activity of a compound based on the difference in the angular velocities of counter-rotating circularly polarized light.
