When liquid 'A' is treated with a freshly prepared ammoniacal silver nitrate solution, it gives bright silver mirror. The liquid forms a white crystalline solid on treatment with sodium hydrogen sulphite. Liquid 'B' also forms a white crystalline solid with sodium hydrogen sulphite but it does not give test with ammoniacal silver nitrate. which of the two liquids is aldehyde? Write the chemical equations of these reactions also.

1.	When liquid 'A' is treated with a freshly prepared ammoniacal silver nitrate solution, it gives bright silver mirror. The liquid forms a white crystalline solid on treatment with sodium hydrogen sulphite. Liquid 'B' also forms a white crystalline solid with sodium hydrogen sulphite but it does not give test with ammoniacal silver nitrate. which of the two liquids is aldehyde? Write the chemical equations of these reactions also.
Answer» SOLUTION :(i) Since liquid 'A' FORMS a white crystaline SOLID on treatment with `NaHSO_(3)`, it may be an aldehyde or a METHYL ketone. Further since liquid 'A' forms a bright silver mirror on treatment with a freshly prepared ammoniacal solution of `AgNO_(3)`, therefore, liquid 'A' is an aldehyde. (ii) Since liquid 'B' forms a white crystalline solid on treatment with `NaHSO_(3)`, it may be an aldehyde or a methyl ketone, Further since liquid 'B' does not give test with ammoniacal `AgNO_(3)` solution, therefore, liquid 'B' must be a methyl ketone. Chemcial equations for the reactions discussed are: .
