Geometric: In general, such isomers contain double bonds, which cannot rotate, but they can also arise from ring structures, wherein the rotation of bonds is greatly restricted. Cis and trans isomers...
plane polarised light is being used. A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form. A solution of the other...
Structural isomers have the same molecular formula but different connectivity. Optical isomers have the same molecular formula but rotate plane polarized light. Optical isomers occur when chiral...
