the higher boiling point of carbon monoxide (co) relative to nitrogen (n₂) is due to the ________ nature of carbon monoxide and the resulting ________ forces.
polar, dispersion
nonpolar, dipole - dipole
nonpolar, dispersion
polar, dipole - dipole

Explanation:

1. For the first question, dipole - dipole attraction is defined as the electrostatic force between the partially positive end of one polar molecule and the partially negative end of another. Nuclear forces act within the nucleus, gravitational forces are between masses, and magnetic forces are related to magnetic fields.
2. For the second question, carbon monoxide (CO) is a polar molecule due to the difference in electronegativity between carbon and oxygen. Nitrogen ($N_2$) is non - polar. The higher boiling point of CO is due to dipole - dipole forces between its polar molecules, while $N_2$ has only dispersion forces.

Answer:

1. A. dipole - dipole
2. D. polar, dipole - dipole
