Explain the isomerism exhibited by carboxylic acids.
Open in App
Solution
Carboxylic acid can exhibit following types of isomerism:-
Chain isomerism → Chain isomerism is exhibited by the compounds which are made up of two or more carbon or other compounds with the same molecular formula but different atomic arrangements, or branches.
E.g.- CH3−CH2−CH2−COOH⇋CH3−CH3|CH−COOH
Functional isomerism → In functional isomerism, the isomer is an isomer with a different arrangement of atoms and also different functional groups.
