Intermolecular Forces

Intermolecular forces play a vital role in determining the properties and behavior of substances. Hydrogen bonding is the strongest type of intermolecular force, commonly seen in compounds containing nitrogen, fluorine, or oxygen.

Intermolecular Forces

Allows Compounds to stay together after forming

Keep Together From What?

Intermolecular Forces

London Forces

Structure
Lipids

Saturated Fats

Makes Stronger London Forces

Which Makes Stronger Intermolecular Forces

Melting/Boiling Point

High

Will not melt at room tempature

Low

Will melt at room tempature

Unsaturated Fats

Makes Weaker London Forces due to structure being further apart

Which makes Weaker Intermolecular Forces

Vegetable Oil

Double Bond

Add Water Getting Rid of Double Bond

Structure Tightens

Hydrated Vegetable Oil

Solubility
With Water

Hydrophilic Compound's

Soluble with water

Polar and Ionic Bonds

Nonpolar bonds

Hydrophobic Compound's

Insoluble with water

Two Same Bond Types

Soluble With Each other

Two Different Bond Types

Insoluble With One Another

Hydrogen Bonding

Strongest Intermolecular Force
Nitrogen, Fluorine, Oxygen
Mustard Powder

Lipids, and Oils (Hydrophobic)

Reacts with the Oil

Creates London Forces

Carbohydrates, Proteins. (Hydrophilic)

Reacts with Vinegar. (Basically Water)

Creates Hydrogen Bonding

Stabilizes mixture of oil and vinegar

Creates Salad Dressing

Dipole Forces

Non Polar
no dipoles

Therefore no Dipole Forces

Polar
Positive and Negative Dipoles

Attract to surrounding dipoles of other molecules

Different mass and size

Weakens Dipole Forces Strength

Similar Mass and Size

Increases Dipole Forces Strength

Strength Also depends on polarity of the molecule
