Question

A carbon compound has many functional groups, then order of preference while naming it according to IUPACnomenclature is
a) - CHO >- COOH >– OH>- NH2, b) - COOH 2> - CHO >- NH2 >– OH
c) - COOH> -OH > - NH2 > - CHO. d) - COOH > - CHO > - OH - NH2. ​

Answer 1

1st -COOH,2nd -CHO,3rd -OH,4th -NH2

Answer 2

Answer:

The correct answer is Option D : $COOH > CHO > OH > NH_2$

Explanation:

• According to the major functional group found in the structure, organic molecules are classified into distinct kinds of compounds under the IUPAC naming system.

• Functional groups with carbon as its centre atom are referred to by the order of precedence.

• As a general rule, the functional group has a higher priority the higher the oxidation state of the central carbon is. As a result, carboxylic acids are given precedence over alcohols, and so forth.
