(a) Give chemical tests to distinguish between compounds in the following pairs of substances :(i) Ethanol and Propanal (ii) Benzoic acid and Ethyl benzoate(b) An organic compound contains 69.77% carbon, 11.63% hydrogen and rest oxygen. The molecular mass of the compound is 86. It does not reduce Tollen’s reagent but forms an addition compound with sodium hydrogen sulphite and gives positive iodoform test. On vigorous oxidation it gives ethanoic and propanoic acids. Derive the structure of the compound.
