- Compound C is CH3COOH
- Compound R is CH3COONa
- Compound A is C2H5OH
- Compound S is CH3COOC2H5
(1) Compound C is Ethanoic acid (CH3COOH). It reacts with sodium metal to form a compound called R where R is Sodium Ethanoate (CH3COONa).
2CH3COOH + 2Na → 2CH3COONa + H2
(2) Compound S is Ester or Ethyl ethanoate(CH3COOC2H5) and compound A is Ethanol (C2H5OH).
CH3COOH + C2H5OH → CH3COOC2H5 + H20
(3) Compound R is again Sodium Ethanoate
CH3COOC2H5 + NaOH → CH3COONa + C2H5OH
So compound C is Ethanoic acid.
