Final answer:
CH₃OH has stronger dispersion forces than N₂ and CO because it has a larger molecular size and the capacity for hydrogen bonding, while CO has stronger forces than N₂ due to dipole-dipole attractions.
Step-by-step explanation:
When comparing the dispersion forces between CH₃OH, N₂, and CO, we must consider both the molecular mass and whether the molecules are polar or nonpolar. CH₃OH has stronger dispersion forces than N₂ and CO due to its larger molecular size and the presence of a highly polar hydrogen bonding capacity thanks to its -OH group. CO and N₂ both have similar molecular masses; however, CO is a polar molecule and can exhibit dipole-dipole attractions, making its intermolecular forces stronger than those in nonpolar N₂. Therefore, the correct answer is that CH₃OH has stronger dispersion forces than N₂ and CO.
