The correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is (a) $-\mathrm{COOH},-\mathrm{SO}_{3} \mathrm{H},-\mathrm{CONH}_{2},-\mathrm{CHO}$ (b) $-\mathrm{SO}_{3} \mathrm{H},-\mathrm{COOH},-\mathrm{CONH}_{2},-\mathrm{CHO}$ (c) $-\mathrm{CHO},-\mathrm{COOH},-\mathrm{SO}_{3} \mathrm{H},-\mathrm{CONH}_{2}$ (d) $-\mathrm{CONH}_{2},-\mathrm{CHO},-\mathrm{SO}_{3} \mathrm{H},-\mathrm{COOH}$

Key Concepts

IUPAC Nomenclature

This is the standardized system for naming organic compounds established by the International Union of Pure and Applied Chemistry (IUPAC). It provides systematic guidelines that help chemists communicate unambiguously about molecular structures, taking into account factors like the longest carbon chain, substituents, and functional groups.

Functional Group Priority

Within the IUPAC system, functional groups are ranked in order of priority, which influences how compounds are named. The group with the highest priority determines the suffix of the compound's name and influences the numbering of carbon atoms in the main chain, while other groups are named as prefixes.

Suffixes and Prefixes in Nomenclature

Depending on the priority of the functional groups, the highest priority one is cited as a suffix in the compound name, while lower priority groups are listed as prefixes. This system ensures that the most chemically significant features of a molecule are highlighted in its name.
