    Answer to 587088

    1) Chromic acid (K2Cr2O7 in H2SO4) easily oxidizes aldehydes to corresponding carboxylic acids (-CHO to -COOH).
    So the product will be:

    The net ionic reaction is as follows:

    where R = (CH3)2CH-

    2) Tollens' reagent contains the diamminesilver(I) ion, [Ag(NH3)2]+. Aldehydes reduce the diamminesilver(I) ion to metallic silver, forming a grey precipitate of silver or a silver mirror on the test tube. Due to alkaline condition, the aldehyde itself is oxidized to a salt of the corresponding carboxylic acid. ...
