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. [1] [2] This contrasts with structural isomers ... WebGeometric isomerism (also known as cis-trans isomerism or E-Z isomerism) is a form of stereoisomerism.

WebJan 30, 2016 · Optical Isomerism in Thalidomide. January 30, 2016 Hannah Elphick. Thalidomide is a pharmaceutical drug designed to prevent morning sickness during pregnancy but is more well known for the birth defects that it caused. Later chemical analysis confirmed that the organic compound was optically active – but what does this … WebIn structural isomerism, the atoms are arranged in a completely different order. This is easier to see with specific examples. What follows looks at some of the ways that structural isomers can arise. Constitutional isomers arise because of the possibility of branching in carbon chains. For example, there are two isomers of butane, C 4 H 10. In ... reformation 500 sourcebook
