A compound C (molecular formula, C2H4O2), reacts with Na - metal to form a compound R and evolves a gas that burns with a pop sound. Compound C, on treatment with an alcohol A in the presence of an acid forms a sweet smelling compound S (molecular formula, C4H6O2). On addition of NaOH to C, it also gives R and water. S on treatment with NaOH solution gives back R and A. Identify C, R. A, S and write down the reactions involved.
