1. Covalent bonds

3. Polar molecules will be attracted to each other by either hydrogen bonding or dipole-dipole interactions. These intermolecular forces are made possible by a large difference in electronegativity values for two atoms bonded to each other. In water, the electronegativity difference between oxygen (3.5) and hydrogen (2.1) is 1.4 (3.5-2.1=1.4).

4. The strongest intermolecular forces are in ion-ion bonds which happen when a metal bonds to another metal.

The next strongest forces are ion-dipole bonds which happen when metals bond to nonmetals.

The third strongest force is a type of dipole-dipole force called hydrogen bonding.

The rest of the dipole-dipole bonds come next.

5. Types of Intermolecular Forces Exist in CH4 Molecules? What Types of Intermolecular Forces Exist in CH4 Molecules? The molecule known as CH4, or methane, is affected by van der Waals forces between individual molecules

6. intramolecular forces are the bonding of atoms that holds a molecules together intermolecular forces hold molecules together in a solid or liquid. The bonds between hydrogen and oxygen hold the water molecule together. The sharing of electron density creates a bond that holds the two atoms together. So called Hydrogen bonding.
