The \(\mathrm{p} K_a\) values of four carboxylic acids are \(4.76,4.19,0.23\) and 3.41 respectively. The \(\mathrm{p} K_a\) value of strongest carboxylic acid among them is
- A 4.19
- B 3.41
- C 0.23
- D 4.76
Answer & Solution
Correct Answer
(C) 0.23
Step-by-step Solution
Detailed explanation
A stronger acid will have higher \(K_a\) value but smaller \(\mathrm{p} K_a\) value while a weaker acid will have smaller \(K_a\) value but higher \(\mathrm{p} K_a\) value. Hence among the given carboxylic acid the \(\mathrm{p} K_a\) value of strongest acid is 0.23 .
