The \(\mathrm{K}_{\mathrm{a}}\) values of \(\mathrm{A}, \mathrm{B}\) and \(\mathrm{C}\) are \(1.8 \times 10^{-4}, 5 \times 10^{-10}\) and \(3 \times 10^{-8}\) respectively. The correct order of their acidic strength is
- A \(\mathrm{B}>\mathrm{A}>\mathrm{C}\)
- B \(\mathrm{B}>\mathrm{C}>\mathrm{A}\)
- C \(A>B>C\)
- D \(A>C>B\)
Answer & Solution
Correct Answer
(D) \(A>C>B\)
Step-by-step Solution
Detailed explanation
Larger the \(\mathrm{K}_{\mathrm{a}}\) values, higher is the acidic strength.
