Intermolecular Attractions

Match the following molecules to the type of intermolecular attractions

• Cations and anions attracted electronically

• Rocks and gems

• Sea of electrons

• Ionic bonds

• Dispersion Forces

• Polar covalent bonds

• Dipole-Dipole attraction

• Metals and alloys

• Networked covalent bonds

• Nonpolar covalent bonds

Match the following molecules to the type of intermolecular attractions

• Ionic bonds

• Alloys

• Dipole-Dipole attraction or Hydrogen bonding

• Diamond

• Networked covalent bonding

• Two nonmetals with different electronegativities

• Dispersion Forces

• Metal and a nonmetal

• Metallic bonding

• Diatomic elements, noble gases, and hydrocarbons

Match the following molecules to the type of intermolecular attractions

• Dispersion Forces

• Strongest force for covalent bonded molecules, soluble in water. Has H with F, O, or N

• Metallic bonding

• Weakest force, lowest boiling points

• Hydrogen bond

• Weak force, low boiling point

• Ionic bonds

• Stronger because it is a "real" bond. Conducts electricity as a liquid or solution

• Dipole-Dipole attraction

• Conducts electricity always, malleable, ductile

Put the intermolecular attractions in order from weakest to strongest

Weakest ---> Strongest

• Dispersion Forces

• Dipole-Dipole

• Hydrogen Bond

• Ionic Bonds

• Metallic Bonds

Which of these intermolecular attractions are NOT between molecules that have covalent bonds?

• Hydrogen bond

• Dipole-dipole

• Dispersion forces

• Metallic bond

Answer explanation

The metallic bond is not an intermolecular attraction between molecules with covalent bonds. It involves the sharing of a "sea of electrons" and is much stronger

Which of these intermolecular attractions are NOT between molecules that have covalent bonds?

• Hydrogen bond

• Dipole-dipole

• Dispersion forces

• Ionic bond

Answer explanation

Ionic bond is not an intermolecular attraction between molecules with covalent bonds. It involves the transfer of electrons between a metal and a nonmetal

Which type of intermolecular attraction is shown (#1 in the diagram)?

• Hydrogen bond

• Metallic bond

Which type of bonding does this molecule have (careful - not the intermolecular attractions)

• Hydrogen bond

• Covalent bond

• Ionic bond

• Metallic bond
