Rank the following compounds according to their boiling point.
Highest Boiling Point
Lowest Boiling Point
n-butanal 1-butanol butane
butanoic acid
You are looking for intermolecular interactions here.
Butanoic acid has the strongest due to the carboxylic acid group, it can even form a dimer. It will have the highest BP.
Butanol is next. It has hydrogen bonding interactions due to the alcohol.
Then Butanal which has a dipole due to its carboxyl group
Then Butane. It only has van der waals holding it together
