A' and 'B' are two isomeric compounds of the formula C_(2)H_(5)NO. 'A' on treatment with P,Os gives 'C'. Both 'A' and 'C' on alkaline hydrolysis evolve NH_(3). 'B' can be easily prepared from acetaldehyde. ‘A' is amphoteric inature and acid derivative. The structure of ‘A' is

Answer»

`CH_(3)-overset(O)overset(||)C-NH_(2)`
`CH_(3)-CH=NOH`
`CH_(3)-CH_(2)-N=O`
`CH_(3)-overset(O)overset(UARR)N-CH_(3)`

SOLUTION :`CH_(3)-UNDERSET((A))overset(O)overset(uarr)N-CH_(3)overset(P_(2)O_(5))to underset(( C ))(CH_(3)-C-=N)to underset((B))(CH_(3)-overset(N-OH)overset(||)CH)`
