Hi! Intermolecular bonding refers to forces present between two or more 1-butanol molecules. You are right, Hydrogen bonding is one of them. You will also get some dipole-dipole interactions and london dispersion forces. This is due to the polar bond between the terminal oxygen and the carbon chain. I hope this helps! Please don\'t forget to rate : ) Solution Hi! Intermolecular bonding refers to forces present between two or more 1-butanol molecules. You are right, Hydrogen bonding is one of them.
