Optical active compounds
WebIt is important to know that optically active compounds are chiral and optically inactive compounds are achiral. The instrument that is used to put all these parts together and allow for measuring the extent and the direction to which the plane rotates is called a polarimeter. The light source in a polarimeter is usually a sodium lamp, which ...
