JEE Mains · Chemistry · STD 12 - 8.2 Carboxylic acids and their derivative
Arrange the following labelled hydrogens in decreasing order of acidity
- A \(b > c > d > a\)
- B \(c > b > a > d\)
- C \(b > a > c > d\)
- D \(c > b > d > a\)
Answer & Solution
Correct Answer
(A) \(b > c > d > a\)
Step-by-step Solution
Detailed explanation
\(\begin{array}{*{20}{c}} {O\;\;} \\ {||\;\;} \\ {R - C - OH} \end{array} > R - OH > R - C \equiv CH\) Reason: \(\begin{array}{*{20}{c}} O \\ {||} \\ {R - C - {O^\theta }} \end{array}\) stable by equivalent resonance. Stable: So answer is \(b > c > d > a\)
