Cis - trans isomerism

Webgeometric isomerism. There are two conventions used to describe the arrangement of groups across a double bond, E/Z isomerism and cis/trans isomerism. E/Z isomerism . Cis/trans isomerism . Cis/trans isomerism is a special case of E/Z isomerism in which two of the substituent groups (one on each carbon atom of the C=C) are the same. 2. 3. … WebAlso, the presence of a double bond leads to the possibility of cis-trans isomers (geometric isomerism) in certain alkenes. You will learn to identify and draw them. Discussion: Alkenes have carbon - carbon double bonds (C = C) which makes them unsaturated hydrocarbons.
