Vedclass · Answer

(C) The priority order of functional groups in $IUPAC$ nomenclature is determined by established rules. The general order is: $-CONH_2$ (Amide) $>$ $-COOR$ (Ester) $>$ $-CHO$ (Aldehyde) $>$ $>C=O$ (Ketone) $>$ $-CN$ (Nitrile) $>$ $-OH$ (Alcohol) $>$ $-NH_2$ (Amine) $>$ $-C=C-$ (Alkene) $>$ $-C \equiv C-$ (Alkyne).Comparing the provided options:Option $C$ lists: $-CONH_2$ (Amide) $>$ $-CHO$ (Aldehyde) $>$ $>C=O$ (Ketone) $>$ $-NH_2$ (Amine) $>$ $-C \equiv C-$ (Alkyne).This sequence correctly follows the decreasing order of priority for the given groups.

In $IUPAC$ nomenclature,the correct order of decreasing priority of functional groups is:
