Anorganic compound A on treatment with ainmnoniacal silver nitrate gives metallic silver and produces a yellow crystalline precipitate of molecular formula C_(9)H_(10)N_(4)O_(4), on treatment with Brady's reagent. Give the structure of the organic compound A.

Answer»

`CH_(3)CHO`
`CH_(3)COCH_(3)`
`CH_(3)CH_(2)CHO`
`CH_(3)CH_(2)underset(O)underset(||)C-CH_(3)`

Solution :Brady.s reagent is 2,4-dinitrophenylhydrazine.

The COMPOUND is an aldehyde as it gives Tollens. test. So, the crystalline PRODUCT is

So, the compound A is `underset("(Propionaldehyde)")(H_(3)C-CH_(2)-CHO)`.
