select the correct answer from each drop - down menu.
consider the substances hydrogen (h₂), fluorine (f₂), and hydrogen fluoride (hf). based on their molecular structures, how does the boiling point of hf compare with the boiling points of h₂ and f₂?
the boiling point of hf is drop - down menu the boiling point of h₂, and it is drop - down menu the boiling point of f₂.

Explanation:

Step1: Identify intermolecular forces

H₂ and F₂ have London - dispersion forces. HF has hydrogen bonding in addition to London - dispersion forces.

Step2: Compare strength of forces

Hydrogen bonding is a stronger intermolecular force than London - dispersion forces.

Step3: Determine boiling - point relationship

Stronger intermolecular forces lead to higher boiling points. So, HF has a higher boiling point than H₂ and F₂.

Answer:

The boiling point of HF is higher than the boiling point of H₂, and it is higher than the boiling point of F₂.
