CHEM: Lesson 7

The force that holds atoms together within a molecule.

• Intermolecular Forces

• Intramolecular Forces

It is the attraction between molecules.

• Intermolecular Forces

• Intramolecular Forces

Determine whether a compound is a solid, liquid or gas at a given temperature (determine melting and boiling points of substances).

• Intermolecular Forces

• Intramolecular Forces

Are an attractive force between ions with opposite charges. 

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction

• Dispersion Forces

They are also referred to as ionic bonds and are the forces that hold together ionic compounds.

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction

• Dispersion Forces

It is an attractive force that results from the electrostatic attraction between an ion and a neutral molecule that has a dipole.

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction

• Dispersion Forces

Most commonly found in solutions. Especially important for solutions of ionic compounds in polar liquids.

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction

• Dispersion Forces

A positive ion (cation) attracts the partially negative end of a neutral polar molecule. A negative ion (anion) attracts the partially positive end of a neutral polar molecule.

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction

• Dispersion Forces

Attraction formed between the hydrogen atom of one molecule and an electronegative atom of an adjacent molecule (O, N, or F).

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction

• Dispersion Forces

A type of dipole interaction and the strongest intermolecular force.

• Ion-ion interaction

• Ion-Dipole Reaction

• Hydrogen Bonding

• Dipole-Dipole Interaction
