Chemistry - CHEMISTRY IN EVERYDAY LIFE Question with Solution | TestHub

Question Explanation:  

The question asks to identify the parent compound or basic structure from which all sulpha drugs (sulfonamides) are chemically derived.

Concept:

This question is based on  classification of drugs.

Solution:  

Sulpha drugs, which are a class of antimicrobial agents, are structural analogs of p-aminobenzoic acid but are chemically derived from Sulphanilamide (p-aminobenzenesulphonamide). 

Sulphanilamide is considered the simplest and parent compound of this group, with other sulpha drugs being formed by substitution on the amide nitrogen atom.
