The polarity of a bond is determined by...

• The sum of the electronegativities of the two atoms

• The difference in the electronegativities of the two atoms

• The charges of the atoms

• The number of electrons shared in the bond

Ion-dipole interactions are most significant in solutions where:

• The solvent is nonpolar

• The solute is a nonpolar gas

• The solvent is polar and the solute is ionic

• Both solute and solvent are ionic compounds

Which of the following best explains why ion-dipole forces are important in the dissolution process of ionic compounds in water?

• They increase the boiling point of the solution

• They help in the formation of hydrogen bonds between water molecules

• They contribute to the stabilization of the ions in the solution by surrounding them with water molecules

• They decrease the freezing point of the solution

Which of the following statements describes a polar molecule?

• because electrons are transferred between atoms, the molecule conducts electricity

• electrons are equally shared between atoms, giving them a negative charge

• the molecule has unequal sharing of electrons, atoms have slightly positive or negative charge

• a polar molecule is perfectly symmetrical, electrons travel freely around atoms

Why are ion-dipole interactions stronger than dipole-dipole interactions?

• Because ions have a complete charge while dipoles only have partial charges

• Because ion-dipole interactions only occur in aqueous solutions

• Because dipole-dipole interactions are temporary

• Because ions are smaller than molecules

Which intermolecular force results from the differing charges of ionic compounds?

• Dipole-Dipole

• Hydrogen Bonding

• London Dispersion

• Ion-Dipole

In a polar covalent bond, the electrons gather around...
