Base pairing
Nitrogen and Hydrogen have high electro negativity difference.So they can form hydrogen bonds.
The question makes no sense. There's no such thing as a "nitrogen bond". If you mean "nitrogen atoms", then there are no hydrogen bonds between nitrogen atoms. If you mean "hydrogen bonds between a hydrogen and a nitrogen", then they break like any other hydrogen bond; they aren't really "bonds", just relatively strong electrostatic forces.
Covalent bonds are formed by sharing electrons between two atoms.
Ionic bonds are based on the electrostatic attraction of ions; covalent bonds are based on the sharing of electrons between two atoms.
Ionic and covalent bonds are both chemical bonds formed by either sharing or transferring electrons. Hydrogen bonds are technically not a kind of chemical bond but a kind of intermolecular attraction between polar molecules in which hydrogen is bonded to one of the very electronegative elements nitrogen, oxygen, or fluorine.

Hydrogen Bonds
The double helix keeps its shape with the help pf intermolecular forces, primarily those of hydrogen bonds. Depending on the combination there could be 2 or 3 H-bonds between the bases.
The intramolecular bonds are stronger.
Covalent bonds are formed by sharing electrons between two atoms.
