Answer:
Correct Answer: 31. ( a )
Solution:
- Carboxylic acid is stronger acid than ammonium ion, hence $-\mathrm{COOH}(X)$ is most acidic. $\mathrm{Z}\left(\stackrel{+}{\mathrm{N}} \mathrm{H} _3\right)$ is more acidic than $Y\left(\stackrel{+}{\mathrm{N}} \mathrm{H} _3\right)$ due to $-I$ effect of $-\mathrm{COOH}$ on $Z$. Hence, overall acid strength order is
$ \quad X>Z>Y $
