When D reacts with C_(2)H_(5)OH then product will be :

A compound 'A' having molecular formula C_(2)H_(5)O_(2)N , on reaction with Sn and conc. HCl gives a compound B which when treated with NaNO_(2) and dil. HCl gave compound C having molecular formula C_(2)H_(6)O . The compound C when treated with Na metal give effervescenes and when reacts with CrO_(3) give a saturated aldehyde having 2 carbon atoms. Determine the structures and names of A, B and C along with the sequence of reactions.
