What type of van der Waals interactions occur between molecules
BigorU [14]

Given what we know, we can confirm that the type of van der Waals interactions that occur between molecules of O2, SCl2, and CH4 in liquids of these substances are the presence of <u>London dispersion forces</u>.

<h3>What are London dispersion forces?</h3>
  • They are a force of attraction between atoms.
  • They are generated by electrostatic attraction.
  • These forces are common between atoms in close proximity and occur often when compounds have a symmetrical distribution of atoms.
  • They are generated by the formation of temporary dipoles.

Therefore, given the symmetry of the atoms disposition in these compounds and the temporary dipoles generated by the atoms being in close proximity, we can confirm that the van der Waals forces present in each compound are London dispersion forces.

Use molecular orbital theory to determine whether He2 2+ or He2 + is more stable. Use molecular orbital theory to determine whet
julia-pushkina [17]

Answer:

The He₂ 2+ ion is more stable since it has a higher bond order (bond order = 1) than the He₂ + ion (bond order = 1/2).

Explanation:

Molecular orbital of He₂⁺

1\sigma_{1s}^21\sigma(star)_{1s}^1

There are two electrons in bonding and 1 electron in antibonding orbital

Bond order = \frac{(2-1)}{2}    

= \frac{1}{2}

Molecular orbital of He₂⁺²

1\sigma_{1s}^21\sigma(star)_{1s}^0

There are two electrons in bonding and 0 electron in antibonding orbital

Bond order = \frac{(2-0)}{2}

= 1

So bond order of He₂⁺² is 1 which is more stable than He₂⁺ whose bond order is   \frac{1}{2}   .
