Which of the following compounds give(s) positive test with Tollens' reagent?A. Carboxylic acidB. AlcoholC. Alpha hydroxy ketonesD. Aldehydes
A
(A) A and B
B
(B) B and C
C
(C) A, B and D
D
(D) C and D
Answer
(D) C and D
Explanation
Solution
Explanation:
Alpha hydroxy ketones and Aldehydes give a positive test with Tollens' reagent.Ketones generally don’t give positive test with Tollen’s reagent, but alpha hydroxyl ketones are an exception. Iodoform test, Ester test, etc., are used for alcohols. The litmus test, Sodium bicarbonate test and Ester test are used for carboxylic acid.Hence, the correct option is (D).
