(9) Benzaldehyde does not show positive test with(a) Schiff reagent(b)

1.	(9) Benzaldehyde does not show positive test with(a) Schiff reagent(b) Tollen's reagent(c) Fehlin solution(d) Sodium bisulphite solution
Answer» 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)... Hope it will help you.... don't forget to LIKE and follow my account
