Question

$\textbf{Match List I with List II}$
\begin{array}{|c|c|c|} \hline \text{List I (Compound)} & \text{List II (p}K_a\text{ value)} \\\ \hline \text{A. Ethanol} & \text{I. } 10.0 \\\ \text{B. Phenol} & \text{II. } 15.9 \\\ \text{C. m-Nitrophenol} & \text{III. } 7.1 \\\ \text{D. p-Nitrophenol} & \text{IV. } 8.3 \\\ \hline \end{array}
$\text{Choose the correct answer from the options given below :-}$

• A. A-I, B-II, C-III, D-IV
• B. A-IV, B-I, C-II, D-III
• C. A-III, B-IV, C-I, D-II
• D. A-II, B-I, C-IV, D-III

Answer 1

Answer: (D)

A-II, B-I, C-IV, D-III

Answer 2

The correct matching is as follows:

- A. Ethanol has a $pK$ value of 15.9, so $A - II$.
- B. Phenol has a $pK$ value of 10.0, so $B - I$.
- C. $m$-Nitrophenol has a $pK$ value of 8.3, so $C - IV$.
- D. $p$-Nitrophenol has a $pK$ value of 7.1, so $D - III$.

Hence, the correct matching is $A - II, B - I, C - IV, D - III$.

The Correct Answer is: A-II, B-I, C-IV, D-III
