which intermolecular forces are present for a molecule with the formula nf₃? (pick all that apply) dipole - dipole forces covalent bonding dispersion forces hydrogen bonding question 15 1 pts which intermolecular forces are present for a molecule with the formula bf₃? (pick all that apply) dipole - dipole forces hydrogen bonding covalent bonding dispersion forces

Explanation:

1. For $NF_3$: It is a polar molecule due to the electronegativity difference between N and F and its trigonal - pyramidal shape. So, dipole - dipole forces are present. All molecules have dispersion forces. Covalent bonding is an intramolecular force, not an intermolecular force. And there is no hydrogen bonding as there is no H atom bonded to N, O, or F directly.
2. For $BF_3$: It is a non - polar molecule with a trigonal planar shape. So, there are no dipole - dipole forces. There is no hydrogen bonding as there is no H atom. Covalent bonding is intramolecular. All molecules have dispersion forces.

Answer:

For $NF_3$:

• dipole - dipole forces
• dispersion forces

For $BF_3$:

• dispersion forces
