What were the three oxidising agents used in this PPA?
- Acidified potassium dichromate
- Benedicts solution
- Tollens reagent
Why can mild oxidising agents be used to distinguish between aldehydes and keytones?

Aldehydes react with the mild oxidising agents whereas keytones do not
Why were the reaction mixtures not heated directly using a bunsen burner?

As they are highly flammable
