A compound 'A' formula of `C_(3)H_(6)CI_(2)` on reaction with alkali can give 'B' of formula `C_(3)H_(6)O` or 'C' of formula `C_(3)H_(4). 'B'` on oxidatrtion gave a compound of the formula `C_(3)H_(6)O_(2).'C'` with dilute `H_(2)SO_(4)` containing `Hg^(2+)` ion gave 'D' of formula `C_(3)H_(6)O` which with bromine and alkali gave the sodium salt of `C_(2)H_(4)O_(2)`. Then 'A' is
