Question

An organic compound (A) reacts with ethanol to give (B) and (C). On acid hydrolysis (C ) yields (B) and (D). oxidation of (D) gives (B). (B) is an acid and forms a salt with `Ca(OH)_(2)` which on dry distillation gives (E ), `C_(3)H_(6)O`. Give the structures of (A) to (E ) with proper reasoning.

Answer 1

`underset("Acetic anhydride")underset((A))((CH_(3)CO)_(2)O)+C_(2)H_(5)Ohtounderset("Acetic acid")underset((B))(CH_(3)COOH)+underset("Ethyl acetate")underset((C))(CH_(3)COOC_(2)H_(5))`
