Vedclass · Answer

(A) (dextrorotatory) and $l$ (laevorotatory) isomers are enantiomers of each other.Enantiomers have identical physical properties (like melting point,boiling point,solubility in achiral solvents,and dipole moment) and identical chemical properties in an achiral environment.However,they differ in their interaction with plane-polarized light $(PPL)$.$d$-isomers rotate $PPL$ to the right (clockwise),while $l$-isomers rotate $PPL$ to the left (anticlockwise) by the same magnitude.

In which property do $d$ and $l$ isomers differ?
