The lone pair hybrid model can also be applied when evaluating the aromaticity of larger compounds (shown above). Each alkyne accounts for the possibility of either of its carbon atoms receiving both pi electrons in the lone pair hybrid formed. These carbon atoms can now be calculated as sp -hybridized according to both the inclusive and non-inclusive approach, and the compound now satisfies the conjugated pi system requirement for aromaticity. The lone pair hybrid can be further analyzed to see that there are 14 pi electrons (12 from the pi bonds and 2 from the radicals), and since 14 is a Huckel number and the compound meets the rest of the requirements for aromaticity, the compound is aromatic.
