An organic compound A ( molecular formula C , H , O ) gives positive 2,4 DNP test . On treating with iodine and sodium hydroxide it gives yellow precipitate of compound B. Compound A does not give Tollen and Fehling test . On drastic oxidation with potassium permanganate it forms a carboxylic acid C ( molecular formula C - H₂O₂ ) which is also formed with yellow compound in the above reaction . Identify A , B and and write the related reactions .
