A compound A (C2H4O2) reacts with Na metal to form a compound ‘B’ and evolves a gas which burns with a pop sound. Compound ‘A’ on treatment with an alcohol ‘C’ in presence of an acid forms a Sweet smelling compound ‘D’ (C4H8O2). On addition of NaOH to ‘D’ gives back B and C. Identify A, B, C and D write the reactions involved.
Answers
A compound A (C2H4O2) reacts with Na metal to form a compound ‘B’ and evolves a gas which burns with a pop sound. This compound A is ethanoic acid and the gas produced is hydrogen.
Compound ‘A’ on treatment with an alcohol ‘C’ in presence of an acid forms a Sweet smelling compound ‘D’ (C4H8O2). This compound D is an ester, Ethyl ethanoate (CH3COOCH2CH3)
On addition of NaOH to ‘D’ gives back B and C.
A- Ethanoic acid.
B- potassium ethanoate
C- ethanol
D- ethylethanoate.
