3. Covalent bond
"A covalent bond... involves the sharing of electron pairs between atoms." (Wikipedia: Covalent bond, 7.7.21 UTC 10:04)
4. Dipole-dipole interaction

8. Ionic bond
"Ionic bonding... involves the electrostatic attraction between oppositely charged ions or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds." (Wikipedia: Ionic bond, 6.5.21 UTC 16:00)
9. London dispersion force
"London dispersion forces... are a type of force acting between atoms and molecules... The electron distribution around an atom or molecule undergoes fluctuations in time.

"A quadruple bond is a type of chemical bond between two atoms involving eight electrons." (Wikipedia: Quadruple bond, 7.8.21 UTC 13:05)
12. Sigma bond
"Sigma bonds are the strongest type of covalent bond due to the direct overlap of orbitals, and the electrons in these bonds are sometimes referred to as sigma electrons." (Wikipedia: Sigma bond, 7.26.21 UTC 14:25)
