The diagram above shows how the pi electrons from the pi bond in the alkyne that does not contribute to the conjugated pi system of benzyne can be pushed onto either carbon involved in the alkyne. We then take this further by showing the formation (dotted arrow pushing) of a lone pair hybrid where the dotted arrow pushing represents how the pi electrons of that pi bond can gravitate towards either atom and form a lone pair on either of them, which is represented by the open circles above each carbon atom that was involved in the alkyne. In other words, the open circles represent the possibility of delocalization onto that carbon atom rather than the actual occurrence. This is similar to our idea of resonance hybrids in that they represent the possibility of resonance throughout the entire compound (or specific areas of the compound) without necessarily proceeding with that delocalization; the possibility of resonance throughout the compound is being represented in the hybrid model. Our lone pair hybrid model agrees with this logic but specifically for the delocalization of electrons on alkynes. The partial negative charges are an additional way of showing how that carbon atom could have those electrons from the pi bond but do not actually have them, so instead of a full negative charge that would result from the electrons fully delocalized onto that carbon atom we put partial negative charges instead. In this context, the partial negative charges must be used in conjunction with the open circles so that users of this model do not mistakenly think one of the carbon atoms is more electronegative than the other, which would be an incorrect interpretation of the partial negative charges when utilizing the lone pair hybrid model. The lone pair hybrid structure can be evaluated to determine the compound's aromaticity through application of the inclusive vs. non-inclusive steric number calculation method since the two carbons that were involved in the alkyne can now be considered sp 2 -hybridized through either the inclusive or non-inclusive approach (Non-inclusive; 2 sigma bonds + 1 localized lone pair = 3, sp 2 . Inclusive; 2 sigma bonds + 1 lone pair = 3, sp 2 ). The lone pair used in the steric number calculations is the hypothetical lone pair that can form on the atom (represented by the open circles). Further evaluation of the lone pair hybrid model of benzyne shows that it has 6 pi electrons (3 pi bonds) which is a Huckel number, so we consider the compound as aromatic (correct configuration of benzyne in regards to its aromaticity ).
