Sulfa drugs are derivatives of:
Show Hint
- benzoic acid
- sulphanilic acid
- sulphanilamide
- p-aminobenzoic acid
The Correct Option is B
Solution and Explanation
Step 1: Understanding sulfa drugs.
Sulfa drugs are a group of synthetic drugs that contain the sulfonamide group, derived from sulphanilic acid. These drugs are primarily used as antibiotics.
Step 2: Explanation of options.
- (B) Sulphanilic acid is the correct precursor for sulfa drugs.
- (A) Benzoic acid is not the direct precursor for sulfa drugs.
- (C) Sulphanilamide is a product of sulphanilic acid, not the precursor.
- (D) p-Aminobenzoic acid is not the direct precursor for sulfa drugs.
Final Answer: \[ \boxed{\text{B) sulphanilic acid}} \]
