In valence bond theory promotion of a paired electron is its excitation to an empty orbital at higher energy during bond formation This energy input is worthwhile so long as it is less than the energy released through the formation of the extra bonds In the case of carbon we have the electron configuration 2s22px12py1 Promotion of one of the paired electrons in the 2sorbital into the vacant 2pz orbital results in us having four unpaired electrons We are now able to form four bonds by pairing the spins of these electrons with unpaired
