Chapter 9, Problem 71c,d
Consider the H2+ ion. (c) Write the electron configuration of the ion in terms of its MOs. (d) What is the bond order in H2+?
Verified step by step guidance1
Identify the molecular orbital configuration for the H2+ ion.
Recall that H2+ has one electron, which will occupy the lowest energy molecular orbital.
Determine the number of electrons in bonding and antibonding orbitals. For H2+, there is 1 electron in the bonding orbital and 0 in the antibonding orbital.
Use the bond order formula: Bond Order = (Number of electrons in bonding orbitals - Number of electrons in antibonding orbitals) / 2.
Substitute the values into the bond order formula to find the bond order for H2+.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Molecular Orbital Theory
Molecular Orbital Theory explains how atomic orbitals combine to form molecular orbitals, which can be occupied by electrons. In diatomic molecules, these orbitals can be bonding, antibonding, or non-bonding. The arrangement of electrons in these orbitals determines the stability and properties of the molecule.

Molecular Orbital Theory
Bond Order
Bond order is a measure of the number of chemical bonds between a pair of atoms. It is calculated as the difference between the number of bonding and antibonding electrons divided by two. A higher bond order indicates a stronger bond and greater stability of the molecule.

Electron Configuration of Ions
The electron configuration of ions involves determining how electrons are arranged in molecular orbitals for charged species. For the H2+ ion, one electron is removed from the H2 molecule's bonding orbital, affecting the bond order and overall stability of the ion. Understanding this configuration is crucial for calculating bond order.
