Question

define cis and transe

Answer 1

Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is aterm used in organic chemistry. ...Cis and trans isomers occur both in organic molecules and in inorganic coordination complexes

Answer 2

cis indicates that the functional group are on the same side of the carbon chain.while trans conveys that functional groups are on opposing sides of the carbon chain. Cis-trans isomers are steriomers, that is, pairs of molecules which have the same formula but whose functional groups are rotated into a different orientation in three-dimensional space.
