Ethanal and propanal are aldehydes having a different number of carbon atoms per molecule. The best way to distinguish between ethanal and propanal is by performing the iodoform test. Tethanal responds to the iodoform test whereas propanal does not respond to the iodoform test.

Aldehydes and ketones having at least one methyl group linked to the carbonyl carbon atom responds to the iodoform test. Ethanal having one methyl group linked to the carbonyl carbon atom responds to this test. But propanal does not have a methyl group linked to the carbonyl carbon atom and thus, it does not respond to this state.

Etanol and propanol can be distinguished by iodoform test. in this case only ethanol gives this test as it contains an CHOH group whereas propanol does not contain it. also iodoform test distinguishes between primary and secondary alcohols from three carbons (i) Ethanol and 2 propanol. (ii) Aniline and ethylamine.

Give simple chemical tests to distinguish between the following pairs of compounds: Iodoform Test: Ethanal gives iodoform test. Propanal does not give this test. CH 3 CH 2 CHO + 4NaOH + 3I 2 → No Reaction.

Among the given compounds ethanol is alcohol whereas ethanoic acid is a carboxylic acid. When treated with metal carbonates, ethanol shows no reaction whereas ethanoic acid shows a positive reaction by forming products such as salt, water, and carbon dioxide. (3) Soaps and Detergent

Can Tollen’s reagent be used to distinguish between propanal and ethanal? “Distinguishing” implies taking advantage of some difference between the candidates. As Tollens’ reagent is a test for aldehydes, that’s no way to differentiate between two aldehydes.

We can see that only Tollens reagent reacts with ethanal but not propanone. The other reagents react in the same manner with both the functional groups.
