Question
Predict the order of increasing vapor pressure at a given temperature for the following compounds:
CH3CH2CH2CH2OH
HOCH2CH2CH2OH
CH3CH2OCH2CH3
CH3CH2CH2CH2OH
HOCH2CH2CH2OH
CH3CH2OCH2CH3
Answers
Vapor pressure is another way of saying decreasing boiling point. Lower molar masses mean lower boiling points. More hydrogen bonding means higher boiling points.
