Non- Covalent Forces

Intermolecular forces by strength

1. H-bonfing

2. dipole-dipole interaction

3. fleeting dipole dipole interaction

H-bonding

A molecule with a polar with a hydrogen. Creating partial positive hydrogen and partial negative EN atom.

Dipole-Dipole moment

Polar molecules (without a hydrogen) are attracted to one another.

Fleeting Dipole Dipole moments

Molecules with large surface area have large electron clouds that push the electron clouds of other molecule. This creates an induced dipole moment
larger the surface area, stronger the interactions

Branches reduce surface area
