Question

which intermolecular forces are present for a molecule with the formula nh₃? (pick all that apply) dispersion forces hydrogen bonding dipole - dipole forces covalent bonding question 17 1 pts which intermolecular forces are present for a molecule with the formula so₂? (pick all that apply) dipole - dipole forces covalent bonding dispersion forces hydrogen bonding

Explanation:

1. For $NH_3$:

• All molecules have dispersion forces.
• $NH_3$ is a polar molecule with a net - dipole moment, so it has dipole - dipole forces.
• It also has hydrogen bonding because hydrogen is bonded to a highly electronegative nitrogen atom. Covalent bonding is an intramolecular force, not an intermolecular force.

1. For $SO_2$:

• All molecules have dispersion forces.
• $SO_2$ is a polar molecule with a bent shape, so it has dipole - dipole forces. There is no hydrogen bonded to a highly electronegative atom like N, O, or F, so no hydrogen bonding. Covalent bonding is intramolecular.

Answer:

For $NH_3$: dispersion forces, hydrogen bonding, dipole - dipole forces
For $SO_2$: dipole - dipole forces, dispersion forces
