Diethyl ether has a boiling point of 34.5C, and 1 -butanol has a boiling point of 117C : Both of these compounds have the same numbers and types of atoms. Which intermolecular force of attraction best explains the difference in their boiling points? 1-Butanol is capable of hydrogen bonding, while diethyl ether is not. 1-Butanol is polar, while diethyl ether is not. 1-Butanol has greater London dispersion forces than diethyl ether. There's no good explanation to the difference in boiling point
