Polarity/Double Replacement Recap

Which molecule contains a polar bond?

• PS₂

What determines the polarity of a bond?

• The molecular weight of the compound

• The geometric shape of the molecule

• The difference in electronegativity between the atoms

• The size of the atoms

Which of the following is a characteristic of a double replacement reaction?

• Formation of a precipitate

• Release of a gas

• 2 Reactants produce 2 Products

• One Reactant produces 2 Products

How do you determine if a molecule is polar?

• By checking if it has polar bonds and if the molecule is symmetrical

• By checking if it has nonpolar bonds only

• By checking if it dissolves in water

• By checking the molecular weight

Which bond is the most polar?

What is the main reason molecules are polar?

• The presence of hydrogen bonds

• The unequal sharing of electrons between atoms

• The molecular weight of the compound

• The presence of ionic bonds
