Which one of the following reagents will distinguish between benzaldehyde, C6H5CHO, and phenylethanone, C6H5COCH3?
C6H5CHO, being an aldehyde, reduces [Ag(NH3)2]+ (Tollen’s reagent) to give a silver mirror but C6H5COCH3being a ketone, is unable to. C6H5CHO + 2[Ag(NH3)2]++ 3OH- → C6H5CO2- +2Ag + 4NH3 + 2H2O
C6H5CHO, being an aldehyde, reduces [Ag(NH3)2]+ (Tollen’s reagent) to give a silver mirror but C6H5COCH3being a ketone, is unable to.
C6H5CHO + 2[Ag(NH3)2]++ 3OH- →
C6H5CO2- +2Ag + 4NH3 + 2H2O
