1. Draw three molecules of each compound below. a. propane, CH,CH,CH, b. heptane, CH,CH₂CH₂CH₂CH₂CH₂CH, c. 1-propanol, CH₂CH₂CH₂OH d. 1-heptanol, CH₂CH₂CH₂CH₂CH₂CH₂CH₂OH Example: CH,CH₂CH, CH₂CH₂CH₂ CH₂CH₂CH₂ 2. For each compound, consider whether or not hydrogen bonding can occur between its molecules. Use a dashed line to show any hydrogen bonding. 3. For each compound, consider whether or not any polar bonds are present. a. Use a different-coloured pen to identify any polar bonds. b. Which compounds are polar? Which compounds are non-polar? Explain your reasoning. 4. Compare your drawings of propane and heptane. a. Which compound has stronger dispersion forces? Explain your answer. b. Which compound has a higher boiling point? Explain your answer. 5. Compare your drawings of 1-propanol and 1-heptanol. a. Which compound is more polar? Explain your answer. b. Which compound is more soluble in water? Explain your answer. Analysis 1. Which compound has a higher solubility in water? a. a polar compound or a non-polar compound b. a compound that forms hydrogen bonds with water, or a compound that does not form hydrogen bonds with water CH CH CH OH or CH CH CH CH CH₂OH C. 2. Which compound has stronger attractions between molecules? a. a polar compound or a non-polar compound b. a compound without O-H or N-H bonds, or a compound with O-H or N-H bonds 3. Which compound is likely to have a higher boiling point?
