Strong

High M.P. \=\_____________________________________IMF

Strong

High B.P. \=\______________________________________IMF

Strong

Large Molar Mass \=\_____________________Dispersion Forces

Stronger

Strongest IMF, occurs in molecules that contains H-F, H-N, or H-O bond

Hydrogen Bonding

Weakest IMF, caused by instantaneous dipoles, occurs in all molecules

Dispersion

Medium IMF, caused by permanent dipoles, occurs in polar molecules only

Dipole-Dipole

Cohesion

Attractions between identical substances

Adhesion

Attractions between different substances

Viscosity

Resistance of a liquid to flow

Fluidity

Can flow and diffuse

Intermolecular

Forces between molecules. (dispersion, dipole-dipole, hydrogen bonding)

Dipole-Dipole

Attraction of partial charges in molecules

Surface Tension

Measure of inward pull by inner particles

Ionic

Type of solid that is Brittle with high melting point (Salt is an example)

Examples of Network Covalent Solid

Diamond, Quartz

Examples of Covalent Solids

Ice, dry ice, table sugar

Boiling Point

When vapor pressure is equal to the atmospheric pressure

Vapor Pressure

Pressure of vapor over liquid in a closed container

Condensation

Change of state from a liquid to a gas

Ionic bonds are \_____________ than all IMFs

Ionic (M+nm) are usually \_____________________ at room temperature

Solid

Lone metals are usually \__________________at room temperature

Solid

Covalent compounds state of matter depends on \_______________

IMF Strength
