Where Does Isomerism Occur?

Cis-trans isomers can occur when atoms or functional groups are situated on either end of a rigid carbon-carbon bond, such as a double bond. In this case, restricted rotation about the double bond means that the atoms or groups attached to either end can exist in one of two possible configurations.

Where are isomers formed?

The replacement of one or more atoms by their isotopes can create multiple structural isomers and/or stereoisomers from a single isomer. ); as if the substituent was chlorine instead of deuterium. The two compounds do not interconvert easily and have different properties, such as their microwave spectrum.

Which type of isomerism occurs?

There are two general types of isomers. Constitutional isomers are molecules of different connectivity—analogous to simple bracelets in which the order of red and green beads is different. The second type is stereoisomers. In stereoisomers the connectivity is the same, but the parts are oriented differently in space.
