A compound 'C' with molecular formula C2H4O2 reacts with Na metal to form compound 'R' and evolve a gas which burns with pop sound. 'C' reacts with an alcohol 'A' in presence of an acid to form a compound C2H4O2.  On addition of NaOH to 'C' it gives 'R' and water. 'S' on treatment with NaOH gives back 'R' and 'A'. Identify C,R,A,S and write down the reactions involved.
