WebIt can withdraw electrons by virtue of hyperconjugation into sigma* molecular orbitals. A simple way to think about it is that nitrogen is less electronegative than oxygen, thus it cannot stabilize negative charge as well. Since the nitrogen anion is not as stabilized, it is more reactive and thus a stronger base. WebWater Reactive Materials” for the chemicals.
