A scientist is comparing the properties of the molecules HF and HCl. Unfortunately, he mixes up the beakers containing the molecules. To solve this, he decides to find the boiling point of each. He finds that the molecule in beaker A has a higher boiling point than beaker B. Which molecule is in beaker A and which is in beaker B? Explain your answer. ***Be sure to include the type of intermolecular forces experienced by BOTH molecules when explaining your answer.***
