Which of the following compounds exhibits Schiff test?

Options

  1. AKetones
  2. BCarboxylic acids
  3. CAldehydes
  4. DEthers

Correct answer

C. Aldehydes

Step-by-step solution

Schiff's reagent is a dilute solution of rosaniline hydrochloride (magenta dye) whose pink colour has been discharged by passing SO₂ . When an aldehyde is treated with Schiff's reagent, the pink or magenta colour is restored. Ketones, carboxylic acids, and ethers do not respond to this test. Therefore, aldehydes exhibit the Schiff test. Answer: Aldehydes
