Question

(9) Benzaldehyde does not show positive test with
(a) Schiff reagent
(b) Tollen's reagent
(c) Fehlin solution
(d) Sodium bisulphite solution​

Answer 1

Answer:

Aldehydes such as benzaldehyde, lack alpha hydrogens and cannot form an enolate and thus do not give a positive test with Fehling's solution which is comparatively a weaker oxidizing agent than Tollen's reagent, under usual conditions. Therefore, it tests negative

So, the answer is (c)...
