IMF and IMF Properties

List the strongest to weakest IMFs.

• Hydrogen Bond, London Dispersion, Dipole-dipole

• London Dispersion, Dipole-dipole,

  Hydrogen Bond

• Hydrogen Bond, Dipole-dipole, London Dispersion

• Dipole-dipole, Hydrogen Bond, London Dispersion

Hydrogen Bond is the strongest because

• it is temporary

• H only has 1 electron and when shared unequally creates extreme poles

• It is permanent

• Hydrogen has a very strong electronegativity and pulls on the electrons

A strong IMF increases

• boiling point

• solubility

• flammability

• malleability

Viscosity is

• the resistance to flow

• the resistance to spread out

• the ability to make sheets of metal

• the ability to make wire

A weak IMF will result in a

• high melting point

• high viscosity

• high surface tension

• low surface tension

A hydrogen bond is a covalent bond. True or False

• True

• False, because it is ionic

• False because it has an intramolecular force

• False because it has an intermolecular force

Soap has a polar head and a nonpolar tail.

• True

• False

For something to be soluble

• the solvent IMF must be stronger than the solute IMF

• the solvent IMF must be weaker than the solute IMF

• both IMFs must be weak

• the solute and solvent IMFs must be close to the same strength

The dissolving process is

• the IMF broken between the solute and solvent molecules, new IMF formed between solvent and solute, solvent carries solvent particles further apart

• the IMF is formed between the solute and solvent creating a new substance

• the solvent breaks the bonds of the solute and creates a new bond with the solvent

Why do oil and water not mix?

• Water and oil have similar IMF

• Water and oil's IMFs are too different in strength.
