Question

The correct decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is (A) -CONH2, -CHO, -SO3H, -COOH (B) -COOH, -SO3H, -CONH2, -CHO (C) -SO3H, -COOH, -CONH2, -CHO (D) -CHO, -COOH, -SO3 H, -CONH2

Tardigrade Admin · Accepted Answer

The decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is as follows:

- COO H > - S O_{3} H > - CON H_{2} > - C H O

- COOH functional group has higher priority than

- S O_{3} H, - CON H_{2}

and

- C H O

functional groups.

Q. The correct decreasing order of priority for the functional groups of organic compounds in the $I U P A C$ system of nomenclature is

$- CON H_{2}$ , $- C H O$ , $- S O_{3} H$ , $- COO H$

$- COO H$ , $- S O_{3} H$ , $- CON H_{2}$ , $- C H O$

$- S O_{3} H$ , $- COO H$ , $- CON H_{2}$ , $- C H O$

$- C H O$ , $- COO H$ , $- S O_{3} H$ , $- CON H_{2}$

The decreasing order of priority for the functional groups of organic compounds in the IUPAC system of nomenclature is as follows:
$- COO H > - S O_{3} H > - CON H_{2} > - C H O$
- COOH functional group has higher priority than $- S O_{3} H, - CON H_{2}$ and $- C H O$ functional groups.
