2012 · Shift 1 · Q8

JEE AdvancedChemistryAldehydes Ketones and Carboxylic AcidsMCQ+3 / −1
The carboxyl functional group (−-− COOH) is present in
  1. A
    picric acid
  2. B
    barbituric acid
  3. C
    ascorbic acid
  4. D
    aspirin
View written solutionFree

Correct answer: D

  1. We need to identify which compound actually contains the carboxyl functional group (−extCOOH)(- ext{COOH})(−extCOOH).

  2. Check each option:

    A: Picric acid

    • Picric acid is 2,4,62,4,62,4,6-trinitrophenol.
    • It contains a phenolic −OH-OH−OH group, not a −COOH-COOH−COOH group.
    • So, A is not correct.

    B: Barbituric acid

    • Barbituric acid is a cyclic compound containing carbonyl groups and imide-like −NH-NH−NH groups.
    • It does not contain a free carboxyl group (−COOH)(-COOH)(−COOH).
    • So, B is not correct.

    C: Ascorbic acid

    • Ascorbic acid (vitamin C) is a lactone.
    • It has hydroxyl groups and an ester-like cyclic structure, but no carboxyl group (−COOH)(-COOH)(−COOH).
    • So, C is not correct.

    D: Aspirin

    • Aspirin is acetylsalicylic acid.
    • Its structure contains a carboxylic acid group (−COOH)(-COOH)(−COOH) and an ester group.
    • So, D is correct.

  3. Therefore, the compound containing the carboxyl functional group is:

D: Aspirin\boxed{\text{D: Aspirin}}D: Aspirin​
