The correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is
A.—COOH, —SO3H, —CONH2, — CHO✓ Correct
B.—SO3H, —COOH, —CONH2, —CHO
C.—CHO, —COOH, —SO3H, —CONH2
D.—CONH2, —CHO, — SO3H,—COOH
Explanation
The overall order of priority for the functional groups of organic compounds in the IUPAC nomenclature is carboxylic acid > esters> amide > nitrile>aldehydes > ketones > alcohol > amines > hydrocarbons > ethers > alkyl halides Therefore, the correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is 3 2 —COOH —SO H O > —CONH — CH .
