Answer:
The boiling point of HF is higher than the boiling point of H2 and it is higher than the boiling point of H2
Step-by-step explanation:
Here, we want to compare boiling points
The three molecules in question are hydrogen fluoride, hydrogen gas and fluorine gas
The presence of hydrogen bonding in hydrogen fluoride makes it have the highest boiling point. This is because, the higher the intermolecular bonds, the higher the temperature value needed to break these bonds
Thus, what we are saying is that the intermolecular bonds between hydrogen and fluorine is greater than the intermolecular bonds between hydrogen and hydrogen, and fluorine and fluorine
Between hydrogen gas molecule and fluorine gas molecule, hydrogen gas molecule has the lower boiling point. This is because the inter-atomic bond between two fluorine atom is greater than the inter-atomic bond between two hydrogen atoms
