Which of the following reagent give same type of reaction with `HCHO` and `PhCHO`?

Options

A. Fehiling solution
B. `NH_(3)`
C. `NaOH`
D. Tollen's sol.

Answer

C, D

Explanation

`HCHO overset("Fehling solution")(to)HCOOH`
`PhCHO overset("Fehling solution")(to)` No reaction
`HCHO+NH_(3)to(CH_(2))_(6)N_(4)`
`PhCHO+NH_(3)to` `overset(Delta)I(to)PhCH=NH`
`HCH)+NaOHtoCH_(3)OH+HCOO^(-)`
`PhCHO+NaOHtoPhCH_(2)+PhCOO^(-)`
`HCHO overset("Tollens")(to)HCOO^(-)`
`PhCHO overset("Tollens")(tO)PhCOO^(-)`
