Give simple chemical tests to distinguish between the following pairs of compounds : C_(6) H_(5) CHO and C_(6) H_(5) COCH_(3)

Answer»

Solution :`C_(6) H_(5) CHO` being an aldehyde gives silver mirror with Tollen.s reagent WHEREAS `C_(6) H_(5) COCH_(3)` does not.
`C_(6) H_(5) CHO + 2[Ag(OH)_(2) ]^(+) + 3OH^(-) RARR C_(6) H_(5) COO^(-) + underset( "Silver mirror")(2Ag) + 2H_(2) O + NH_(3)`
