The first canonical form(1) is less stable than the second canonical form(2). Because in the first canonical form the positive charge is over the most electronegative oxygen atom where in second canonical form(2) is over the less electronegative N atom . Point should be noted that the less word has used to mean that the electronegativity of N atom is lesser than oxygen atom.
