MCQ
Which gives difference between aldehyde and ketone
- AFehling's solution
- BTollen's reagent
- CSchiff's reagent
- ✓All of these
✓
Answer
Correct option: D.
All of these
d
(d) Fehling solution $⇒$ Alkaline $CuS{O_4} + Na - K$ tartarate
(d) Fehling solution $⇒$ Alkaline $CuS{O_4} + Na - K$ tartarate
Tollen’s reagent $⇒$ $N{H_4}OH + AgN{O_3}$
Schiff’s reagent $⇒$ $P-$rosaniline hydrochloride or magneta
Benedict’s solution $⇒$ Alkaline $CuS{O_4} + $Citrate ions
All these reagents are used to distinguish between aldehydes and ketones.
Aldehydes reacts with all these reagents while ketones do not react.
