Question

Match the class of organic compounds (Column-I) with the suffix used (Column-II).
Column-I: (i) Ketone (ii) Alkene (iii) Aldehyde (iv) Carboxylic acid
Column-II: (A) -al (-CHO) (B) -one (-C=O) (C) -ene (-C=C-) (D) -oic acid (-COOH) — Exam MCQ

A. (i)-(B); (ii)-(C); (iii)-(A); (iv)-(D) — The correct matching of compounds to their IUPAC suffixes is (i)-(B), (ii)-(C), (iii)-(A), (iv)-(D). Ketones are identified by the suffix -one and contain a carbonyl group (C=O) located within the carbon chain. Aldehydes use the suffix -al and have their functional group (-CHO) always located at the end of the carbon chain. Carboxylic acids are characterized by the suffix -oic acid and the functional group (-COOH), which is also terminal.
