Question

What is likely to be the strongest intermolecular force between hexane (C6H14) molecules? (a) Ion-dipole (b) London Dispersion (c) H bonding (d) Ion-induced dipole (e) Dipole-induced dipole 6. What is likely to be the strongest intermolecular force between ammonia (NH3) molecules? (a) Dipole-dipole (b) London Dispersion (c) H bonding (d) Ion-induced dipole (e) Dipole-induced dipole

Answer 1

Hexane molecules exhibit London Dispersion Forces as their strongest intermolecular force, whereas ammonia molecules have hydrogen bonding due to the electronegative nitrogen atom allowing for this stronger intermolecular interaction.

Step-by-step explanation:

The strongest intermolecular force between hexane (C6H14) molecules is likely to be the London Dispersion Forces. Since hexane is a nonpolar molecule with only carbon and hydrogen atoms, it cannot form hydrogen bonds or dipole-dipole interactions, leaving London Dispersion Forces as the predominant intermolecular force. On the other hand, the strongest intermolecular force between ammonia (NH3) molecules is hydrogen bonding. Ammonia has a lone pair of electrons on the nitrogen atom, and hydrogen atoms bound to nitrogen—a highly electronegative atom—which allows for the formation of hydrogen bonds between ammonia molecules.
