What's the strongest intermolecular force present for each of the following molecules

1. Methane

2.Water

3.Ammonia


Sagot :

Answer:

1. Methane (CH₄): London dispersion forces (also known as van der Waals forces). Methane is a nonpolar molecule, so the only intermolecular forces present are weak London dispersion forces.

2. Water (H₂O): Hydrogen bonding. Water molecules are highly polar, and the presence of hydrogen atoms bonded to oxygen (a highly electronegative atom) allows for strong hydrogen bonding between water molecules.

3. Ammonia (NH₃): Hydrogen bonding. Ammonia is a polar molecule with nitrogen bonded to hydrogen, which allows for hydrogen bonding as the strongest intermolecular force between ammonia molecules.
