A

Fehling's solution

B

Schiffs reagent

C

Tollen's reagent

D

Text Solution

Verified by Experts

The correct Answer is:
D
Aldehydes and ketones both can react with 2, 4-dinitrophenyl hydrazine as
`RCH O + H _(2) N. NHC _(6) H _(5) to underset("aldehyde phenyl hydrazone") ( RCH = N. NH C_(6) H _(5)) + H _(2) O `
`R _(2) C O + H _(2) N. NH C _(6) H _(5) to underset("ketone phenyl hydrazone") ( R _(2) C = N. NH C _(6) H _(5) + H _(2)O)`
