How bonding and structure are related to the properties of substances
Question
- A. The number of covalent bonds.
- B. The strength of intermolecular forces.
- C. The size of the atoms in the molecule.
- D. The arrangement of atoms in the molecule.
Answer
The strength of intermolecular forces.
Explanation
The boiling point of a substance is influenced by the strength of the intermolecular forces that must be overcome for the substance to change from liquid to gas.
Common mistake
Confusing Size with Properties
Students often think that larger molecules always have higher melting and boiling points without considering the type of intermolecular forces present.
Emphasize that while larger molecules may have higher melting and boiling points, it is also important to consider the strength of intermolecular forces, which can vary.
