Question

question 1 1 pts what is the strongest intermolecular force present in f₂? dispersion hydrogen bonding dipole - dipole covalent bonding question 2 1 pts what is the strongest type of intermolecular force present in chf₃? hydrogen bonding covalent bonding dipole - dipole dispersion

Explanation:

For Question 1, $F_2$ is a non - polar molecule. Non - polar molecules have only dispersion forces as intermolecular forces. Hydrogen bonding requires hydrogen attached to highly electronegative atoms (N, O, F), and $F_2$ has no such hydrogen situation. Dipole - dipole forces occur in polar molecules, and $F_2$ is non - polar. Covalent bonding is an intramolecular force, not an intermolecular force.
For Question 2, $CHF_3$ is a polar molecule. It does not have hydrogen bonding as hydrogen is not attached to N, O, or F in a way to form hydrogen bonds. Covalent bonding is intramolecular. Dispersion forces are present in all molecules but are weaker than dipole - dipole forces in polar molecules like $CHF_3$.

Answer:

Question 1: dispersion
Question 2: dipole - dipole
