Strength of hydrogen bond is intermediate between:
van der Waal and covalent
Ionic and covalent
Ionic and metallic
Metallic and covalent
As we learn
Electrostatic force > covalent bond > H bond > van der Waal's force
H bond is a strong type of dipole dipole interactions and its strength is intermediate between the van der Waal's forces and strong covalent forces.
Electrostatic force > covalent bond > H - bond > van der Waal's force
Therefore, Option(1) is correct
