Question
### Identifying the Important Intermolecular Forces in Pure Compounds #### Instructions Decide which intermolecular forces act between the molecules of each compound in the table below. Check all that apply. #### Table of Intermolecular Forces | Compound | Intermolecular Forces (check all that apply) | |------------------------|---------------------------------------------| | | Dispersion | Dipole | Hydrogen-bonding | | \( F_2 \) (Fluorine) | ☑️ | ☐ | ☐ | | Nitrogen trichloride | ☐ | ☐ | ☐ | | \( \text{CH}_3\text{F} \) (Fluoromethane) | ☐ | ☐ | ☐ | | Hydrogen fluoride | ☐ | ☐ | ☐ | ### Explanation - **Dispersion Forces**: Also known as London dispersion forces, these are weak intermolecular forces arising from temporary dipoles in molecules. They are present in all molecules but are the only forces in nonpolar compounds. - **Dipole-Dipole Forces**: These occur in polar molecules where there is a permanent dipole moment. - **Hydrogen Bonding**: A special type of dipole-dipole interaction that happens when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Expert Solution
Step 1 Theory

Dispersion forces are present in non-polar molecules.

Dipole forces are present in polar molecules.

Hydrogen bonding is present in molecules in which H is bonded to an highly electronegative atom like F,N and O.

Polar molecules = Molecules having non-zero dipole moment.

Non-polar molecules= Molecules having zero dipole moment.
