Question

Rank these forces from weakest to strongest:

dispersion, dipole-dipole, H-bonds, dipole-induced dipole, ion-induced dipole, and ion-dipole.

Answer 1

You are confusing covalent bonding with Intermolecular forces (H-bonding, dipole-dipole and London Dispersion) .

Covalent bonds are formed between atoms which have
- Unsatisfied valency
- No inert gas electronic configuration
- These are directional bonds
- formed by sharing of electrons

Intermolecular forces
- Much weaker than covalent bond
- These are not directional (except Hydrogen bonds)
- These are more electrostatic in nature
- exist between stable molecules
- can be Hydrogen bonding, dipole-dipole and induced dipole-induced dipole (london dispersion).

covalent > ionic > metallic > h-bonds > dipole-dipole > dispersion

From strongest to weakest:

Now the answer of to your question:
1.Covalent bonding (bonding that happends by the sharing of electrons).
2.Ionic-bonding (most commonly found in salts, it forms by the losing and gaining electrons ** electrons are not shared in this type of bonding).
3.Metallic bonding (between metals only).
4.H-bonding (this type of bonding tends to form with Nitrogen, Oxigen and FLuorine)
5.Dipole-Dipole(forc e that exist because of the interaction of dipoles on polar molecules in close contact).
6.London Dispersion (simultaneously Dipole-dipole moments).
