Answer
a) Ethanoic acid will have a higher boiling point than 1-propanol. This is because two ethanoic acid hydrogen molecules will bond to form a dimer. This dimer will double the molar mass of the ethanoic acid, which will then require a higher temperature to reach boiling point.
b) Ethanoic acid will form hydrogen bonds, while butane will not, because butane only has London Dispersion, meaning it will have a low boiling point.
