What are the three oxidising agents you could use to distinguish between aldehydes and ketones and how they show which each one is?
- Fehling's solution
- Benedict's solution
They are both deep blue Cu2+
complexes, which reduce to brick-red Cu2
O when warmed with an aldehyde but stay blue with a ketone.
- its reduced to silver when warmed with an aldehyde, but not with a ketone. The silver will coat the inside of the apparatus to form a silver mirror.
