Answer:

H2<Ne<O2<NH3

Explanation:

Intermolecular forces refer to the force of attraction between molecules of a substance in any given state of matter whether solid, liquid or gas. Molecules in a substance must be held together by intermolecular forces of attraction. The magnitude of these intermolecular forces of attraction depends on many factors.

For H2, He and O2, the intermolecular force present in these gases are London forces. As the relative molecular mass of individual gas molecules becomes greater, London forces increases significantly with molecular mass. This explains the sequence shown in the answer.

NH3 has the strongest intermolecular interaction because it contains hydrogen bonds since nitrogen is an electronegative element. This a greater intermolecular interaction than dispersion forces.

Intermolecular forces are those forces that bind the molecules of the substance and the polarity of molecules. These forces range from the strongest to the weakest in ion-dipole, hydrogen bonding, and dipole to dipole.

  • H2 being a noble gas has a weak dispersion or a weak dipole force. Ne has an intermolecular force being a noble gas it increases the molecular weight and thus has a modest increase of dipole bounding.
  • The O2 has a strong dipole force than Ne and is stronger due to the two Oxygen molecules. The NH3 has the strongest dipole and intermolecular interaction force. The nitrogen atom strongly pulls the electrons.

Hence the form the strongest to the weakest is NH3, 02, Ne and H2.
