WebThis tutorial explains the concept of optical activity, a special property of chiral compounds. (Runtime = 6:50) • Determine when a molecule will be optically active. • Determine … WebA meso compound is a stereoisomer with two or more chiral centres but no optical activity due to an internal plane of symmetry. Mesomers are compounds with zero net rotation of plane polarised light. In other words, mesomers are organic molecules that have two chiral carbons that are identical, resulting in zero net rotation.
