Question

Draw an MO energy diagram and predict the bond order of He₂⁺ and He₂^-. Do you expect these molecules to exist in the gas phase?

Accepted Answer

BO He₂⁺ = 1/2; BO He₂^- = 1/2

The molecules are expected to exist in the gas phase.

Answer

BO He₂⁺ = 2; BO He₂^- = 2

The molecules are expected to exist in the gas phase.

Answer

BO He₂⁺ = 1; BO He₂^- = 1

The molecules are not expected to exist in the gas phase.

Answer

BO He₂⁺ = 0; BO He₂^- = 0

The molecules are not expected to exist in the gas phase.
