WebMay 17, 2010 · Thalidomide has a tragic history: It was introduced in Germany in 1957 as a sedative and hypnotic and was marketed over the counter largely as a drug for treating morning sickness in pregnant women. In the following few years, about 10,000 infants worldwide were born with phocomelia, or limb malformation. Only half of the infants … 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.

WebFunctional isomers are one of the structural isomers. Two compounds in functional isomerism have the same molecular formula (the number of each atom is the same, like cyclohexane: C 6 H 12 and 1-hexene: C 6 H 12). But, the atoms are connected in other ways so that the groupings are different. 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 enantiomers. A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form.For example, one of the optical isomers ...
Webisomerism: [noun] the relationship of two or more chemical species that are isomers. 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 ...
