A compound C [molecular formula C_2H_4O_2] reacts with Na. metal to form a compound R and evolves a gas which burns with pop sound. Compound C on treatment with alcohol A in the presence of an acid forms a sweet-smelling compound S [molecular formula C_3H_6O_2]. On addition of NaOH to C, it also gives R and water. S on treatment with NaOH solution gives back Rand A. Identify C, R, A, and S and write the reactions involved.

1.	A compound C [molecular formula C_2H_4O_2] reacts with Na. metal to form a compound R and evolves a gas which burns with pop sound. Compound C on treatment with alcohol A in the presence of an acid forms a sweet-smelling compound S [molecular formula C_3H_6O_2]. On addition of NaOH to C, it also gives R and water. S on treatment with NaOH solution gives back Rand A. Identify C, R, A, and S and write the reactions involved.
Answer» SOLUTION :`C: CH_3COOH. "" R: CH_3COONa.` `A: CH_3OH. ""S: CH_3COOCH_3`. Reactions : `2CH_3COOH + 2Na to 2CH_3COONa + H_2` `CH_3COOH + CH_3OH overset(H+)(rarr) CH_3COOCH_3 + H_2O` `CH_3COOH + NaOH to CH_3COONa + H_2O` `CH_3COOCH_3 + NaOH to CH_3COONa + CH_3OH` `underset("Acetic acid")(CH_3 -overset(O)overset(\|\|)(C )-OH) + underset("Ethanol")(HO - CH_2CH_3) overset(H^+)( `underset("ETHYL ACETATE")(CH_3 - overset(O)overset(\|\|)(C )-O -CH_2CH_3) + underset("WATER")(H_2O)`.
