11. Describe the difference between substitution reactions and addition reactions. Your answer should mention the degree of saturation of the organic compound.
Answer: In a substitution reaction, one or more atoms replace an atom or group of atoms in a molecule, so the degree of saturation of the organic molecule is unchanged. In an addition reaction, additional atoms are added to a double or triple bond, so the degree of saturation increases.

12. Explain why some alkanes are gases, others are liquids, and still others are solids at room temperature.
Answer: Very small alkane molecules have very weak London dispersion forces between them, so they are not held together tightly, so these low-mass alkanes are gases. Somewhat larger hydrocarbon molecules, such as those in gasoline and kerosene, have stronger London dispersion forces, so these molecules are held together in liquids. Alkanes that have very high molecular mass have much stronger London dispersion forces, so these compounds are solids.
