NEET 2023 Phase 2 · ChemistryPrevious Year Question

Reagents which can be used to convert alcohols to carboxylic acids are: (A) (B) (C) (D) (E) Choose the most appropriate answer from the options given below.

Answer: (A) (A) (A), (B) and (C) only. \textbf{Answer:} (A) (A), (B) and (C) only \textbf{Solution:} Strong oxidants take a 1 alcohol all the way to a carboxylic acid.

  1. A.(A) (A), (B) and (C) only✓
  2. B.(B) (A), (B) and (E) only
  3. C.(C) (B), (C) and (D) only
  4. D.(D) (B), (D) and (E) only

Correct Answer

(A) (A) (A), (B) and (C) only

Solution & Explanation

\textbf{Answer:} (A) (A), (B) and (C) only \textbf{Solution:} Strong oxidants take a 1 alcohol all the way to a carboxylic acid. (A) (Jones), (B) acidified , and (C) (alkaline then acid work-up) are all strong oxidising systems that give carboxylic acids. (D) at 573 K only dehydrogenates the alcohol to an aldehyde/ketone, and (E) with acetic anhydride is a mild reagent that stops at the aldehyde. Hence only (A), (B) and (C).
