chemical test to distinguish between propanol and propanone

What Tollens test used for distinguishing propanal and propanone?
Tollen's reagent, Bennedict solution and Fehling solution are all used to distinguish between aldehydes and ketones.
Propanal( CH3CHO) is an aldehyde and thus gives positive test with all the three reagents whereas propanone( CH3COCH3) is a ketone and thus does not give any results with the three reagents.
Ferric chloride test: Phenol reacts with neutral FeCl3 to form an iron-phenol complex giving violet colouration.
But benzoic acid reacts with neutral FeCl3 to give a buff coloured ppt. of ferric benzoate.

What is the chemical test to distinguish between propanal and Ethanal?

Iodoform test – Methyl ketones give a positive iodoform test.
Ethanal has one methyl group linked to the carbonyl carbon atom and therefore, responds to this test.
Propanal does not respond to this test.
Propanal being an aldehyde reduces Fehling's solution to form a red-brown precipitate of cuprous oxide._{2 août 2020}
