Identifying intermolecular forces

Postby rosemarywang4i » Wed Nov 28, 2018 3:00 pm

How do you identify the intermolecular forces within a molecule? Are they somehow related to structure and polarity?

Intermolecular forces depend on the polarity of the molecules! Dipole-dipole forces are intermolecular forces between polar molecules, while induced-dipole-induced-dipole forces are between nonpolar molecules.

The more Electronegative the atom the stronger it's force is so a Fluoride is very strong(because of how many valence electrons it has, and how small its atomic radius is) and extremely electronegative when compared to say a regular carbon bond, it's charge isn't entirely negated by bonding so its strong electronegative nature provides an intermolecular force.

Remember that intermolecular forces are not within molecules; they are between different molecules, and include dipole-dipole, hydrogen bonds, and London dispersion forces. Intramolecular forces are the ones that are within molecules, and they include ionic and covalent bonds.

Every interaction between two molecules have London Dispersion Forces. Hydrogen bondings occurs when an H comes into contact with either an F, O, or N atom. Dipole-dipole forces occur that two polar molecules come into contact.
