Question

7. 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.

Answer 1

Reaction involved is
10o28h2s04

Answer 2

Answer:

2 CH₃COOH + 2 Na ⇒  2 CH₃COONa + H₂O

      ( A )                                   ( B )

CH₃COOH + C₂H₅OH ⇒  CH₃COOC₂H₅ + H₂O

                        ( C )                 ( D )

CH₃COOC₂H₅ + NaOH  ⇒ C₂H₅OH + CH₃COONa

Therefore we identified

A - CH₃COOH

B - CH₃COONa

C - C₂H₅OH

D - CH₃COOC₂H₅
