a. Which substance, CH3 CH₂OH or CH3 CH₂ CH₂OH, would be expected to have a lower boiling point? Why? O CH3 CH₂OH, because it has a stronger OH group. OCH3 CH₂ CH₂OH, because it has stronger London forces. OCH3 CH₂OH, because it has a smaller molar mass. OCH3 CH₂ CH₂OH, because it has a larger molar mass. b. Which substance, CH4 or CH3OH, would be expected to have a lower boiling point? Why? OCH4, because only London forces are operating. OCH, OH, because it is capable of hydrogen bonding. OCH4, because it is capable of hydrogen bonding. OCH3OH, because it has larger molar mass. c. Which substance, CH3 CH₂ CH₂OH or CH3 CH₂ CH₂ CH₂ CH3, would be expected to have a lower boiling point? Why? OCH3 CH₂ CH₂OH, because it is capable of hydrogen bonding. O CH3 CH₂ CH2 CH₂ CH3, because it is not capable of hydrogen bonding. OCH3 CH₂ CH2OH, because it has a larger molar mass. OCH3 CH₂ CH2 CH₂ CH3, because it has a smaller molar mass.
