JEE Mains · Chemistry · STD 12 - 8.2 Carboxylic acids and their derivative
The descending order of acidity among the following compounds is:
A. Phenol
B. \(4\)-nitrophenol
C. \(4\)-methoxyphenol
D. \(4\)-nitrobenzoic acid
E. Benzoic acid
Choose the correct answer from the options given below:
- A \(B>D>E>A>C\)
- B \(D>B>E>A>C\)
- C \(C>A>B>D>E\)
- D \(D>E>B>A>C\)
Answer & Solution
Correct Answer
(D) \(D>E>B>A>C\)
Step-by-step Solution
Detailed explanation
Carboxylic acids are stronger acids than phenols because the carboxylate anion is stabilized by equivalent resonance structures. Thus, D and E are more acidic than A, B, and C. For the carboxylic acids, the \(-NO_2\) group in D is an electron-withdrawing group (\(-I, -R\)),…
