Compare the acidities of amide `(R-underset(O)underset (||)(C)-NH_(2))` and sulphonamide `(R-underset(O)underset(||)overset(O)overset(|)S-NH_(2))`

Explanation

To compare the acidities of amide (RCONH₂) and sulfonamide (RSO₂NH₂), we need to analyze the stability of their conjugate bases. The more stable the conjugate base, the stronger the acid.

### Step 1: Identify the conjugate bases
- For amide (RCONH₂), the conjugate base is formed by deprotonating the NH₂ group:
\[ \text{Conjugate base of amide: } RCO^-NH_2 \]
- For sulfonamide (RSO₂NH₂), the conjugate base is formed similarly:
