WebGeometric isomerism. Geometric isomerism is a type of stereoisomerism that occurs in molecules with restricted rotation around a C=C double bonds. Geometric isomers are known as E-Z isomers. Geometric isomerism is caused by C=C double bonds. This is because, unlike C-C single bonds, C=C double bonds can't rotate. WebOptical isomers are named like this because of their effect on plane polarised light. Simple substances which show optical isomerism exist as two isomers known as …

WebSome real examples of optical isomers. Butan-2-ol. The asymmetric carbon atom in a compound (the one with four different groups attached) is often shown by a star. It's extremely important to draw the isomers correctly. Draw one of them using standard bond notation to show the 3-dimensional arrangement around the asymmetric carbon atom. WebStereochemistry focuses on stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
