Arrange the following chemical bonds/interactions in the order of their strengths in vacuum -
Hydrogen bond, Covalent bond, van der Waals attraction and Ionic bond:
1
Covalent bond > Ionic bond> hydrogen bond > van der Waals attraction
2
Ionic bond> Covalent bond > hydrogen bond > van der Waals attraction
3
Covalent bond > Ionic bond > van der Waals attraction > hydrogen bond
4
Ionic bond > Covalent bond > van der Waals attraction > hydrogen bond
