An aldehyde can be distinguished from a Ketone by the use of reagent
As we learnt in
Oxidation of aldehydes with Tollen's reagent / silver mirror test -
– Distinguish aldehydes from ketones
.– Tollen's reagent = ammoniacal silver nitrate solution.
Oxidation of aldehydes with Fehling's solution -
– Fehling solution A is aqueous copper sulphate, Fehling solution B is alkaline sodium potassium tartrate (Rochelle salts)
– Distinguished aldehydes from ketones.
Beside Tollen's reagent and Fehling's solution, Schiff's reagent is also used to distinguish aldehydes and ketones.
