The product of acid hydrolysis of \((P)\) and \((Q)\) can be distinguished by
1 Lucas reagent
2 2,4-DNP
3 Fehling's solution
4 \({\rm{NaHS}}{{\rm{O}}_{\rm{3}}}\)
Explanation:
The product of (P) and (Q) are \(\because\) Fehling solution cannot be reduced with acetone.Thus it can be used to differentiate ketone (acetone) and aldehyde.
