The correct order of `K_(b)` value of following is `(C_(2)H_(5))_(2)overset(..)(N)H,NH_(3)overset(..)(N)(C_(2)H_(5))_(3)`

The correct stability order of the following resonance structure is : (I) H_(2)C= overset( +)(N) =overset( -)(N) (II) H_(2)overset( +)(C )-N = overset( -)(N) (III) H_(2)overset( -)(C ) - overset( +)(N) = N (IV) H_(2)overset( - ) (C ) -N = overset( +)(N )

The correct order of stability of the following resonance structures is (I) H_(2)C = overset(+)(N)= overset(-)(N) " " (II) H_(2)overset(+)(C )-N = overset(-)(N) (III) H_(2)overset(-)(C )-overset(+)(N)-=N " " (IV) H_(2)overset(-)(C )N = overset(+)(N)

IUPAC name of C_(2) H_(5)-overset(CH_(3))overset(|)(C H) - NH_(2) is
