Benzaldehyde being an aldehyetereduces Tollen s reagent to give a red-brown precipitate of Cu2O, but acetophenone being a ketone does not. (b) Sodium bicarbonate test:Acid reacts with NaHCO3to produce brisk effervescence due to evolutionof CO2gas. As benzoic acid is an acid, it gives a positive test while ethylbenzoatedoes not.

Acetaldehyde and benzaldehyde can be differentiated by : A Fehling test B Iodoform test C Tollen’s reagent D both (a) and (b) Hard Open in App Solution Verified by Toppr Correct option is D) (Refer to Image 1) For iodoform test one methyl must be there with carbonyl group. Thus acetaldehyde will give iodoform test and benzaldehyde does not.

For iodoform test one methyl must be there with carbonyl group. Thus acetaldehyde will give iodoform test and benzaldehyde does not. (Refer to Image 2) In Fehling test, enolate formation takes place, thus Aldehydes that lack alpha hydrogen cannot form an enolate and thus do not give a positive Fehling’s test.

Thus acetaldehyde will give iodoform test and benzaldehyde does not.
Which aldehyde will give a positive iodoform test?
If an aldehyde gives a positive iodoform test, then it must be acetaldehyde since it is the only aldehyde with a CH3C=O group. Given below are a few example reactions for positive iodoform tests.
Why benzaldehyde does not give Fehling test?
Thus Benzaldehyde do not give Fehling test as it do not have α−Hydrogen. While Acetaldehyde have 3α−Hydrogen thus it can form enolate and undergo Fehling test. Thus Benzaldehyde & Acetaldehyde can be differentiated using Iodoform and Fehling test.
How can you tell if an aldehyde is acetaldehyde?
If an aldehyde gives a positive iodoform test, then it must be acetaldehyde since it is the only aldehyde with a CH3C=O group. Given below are a few example reactions for positive iodoform tests. First, the Hydroxide ion removes an acidic alpha hydrogen. This results in the formation of an enolate ion.
