Vedclass · Answer

(D) Aldehydes are easily oxidised to carboxylic acids by mild oxidising agents like Tollen's reagent,Fehling solution,and Benedict solution,whereas ketones are resistant to oxidation by these reagents.$1.$ Tollen's reagent: $RCHO + 2[Ag(NH_3)_2]^+ + 3OH^- 	o RCOO^- + 2Ag + 4NH_3 + 2H_2O$$2.$ Fehling solution: $RCHO + 2Cu^{2+} + 5OH^- 	o RCOO^- + Cu_2O + 3H_2O$$3.$ Benedict solution: Similar to Fehling solution,it contains $Cu^{2+}$ ions which oxidise aldehydes.Therefore,the correct option is $D$.
