Using MO theory (but w.o drawing a MO diagram) predict whether HHe or HHe+ would be more stable.
I believe HHe+ would be more stable as the bond order would be 1 (i.e. BO=(2-0)/2) while BO for HHe is 1/2.
Please confirm! thanks!

calculate the amount of isopentyl acetate that should be present in the reaction mixture at equilibrium, based on the quantities of starting materials you used and a value of 4.2 for the equilibrium costant
In QC, the bond order of HHe+ is 0. (1-1)
To predict the stability of HHe and HHe+, you can use the molecular orbital (MO) theory. In MO theory, you can determine the stability of a molecule by analyzing the bonding and antibonding orbitals.
For HHe, you would consider the combination of the 1s orbital of hydrogen (H) and the 1s orbital of helium (He). When these two atomic orbitals combine, they form a bonding molecular orbital (σ). The occupation of this molecular orbital will depend on the number of electrons present.
HHe has two electrons occupying the bonding molecular orbital. This results in a bond order of 1/2. A bond order less than 1 indicates a weaker bond. Therefore, HHe is less stable compared to HHe+ when considering only MO theory.
If we remove one electron from HHe to form HHe+, then there is just one electron occupying the bonding molecular orbital. This results in a bond order of 1, indicating a stronger bond. This suggests that HHe+ would indeed be more stable than HHe based on MO theory.
It is important to note that this prediction is solely based on MO theory and does not take into account other factors such as electrostatic interactions or the overall energy of the system.
