Question:

Dioxygen, O2, has sometimes been represented by the electron-dot formula

Note, however, that this formula implies that all electrons are paired. Give the molecular orbital description of the state of the O2 molecule of lowest energy in which all electrons are paired in this way. Compare this configuration with that of the ground state of O2. In what way are they similar, and in what way are they different?
