So for VSPER, when dealing with radicals, do we account for singular electrons as electron dense regions? For example in CH2+, since the Lewis structure has two bonds, one lone pair and a single electron to the carbon, are there three or four electron dense regions? Will the lone electron affect the molecular shape the same way a lone pair does?
Still consider the electron as a region of electron density, but understand the shape will be somewhat different. A single electron will not exert as much force on surrounding atoms as a lone pair. For example, NO2+ has a bent shape with an O-N-O bond angle of greater than 120 as opposed to less than.
In the textbook it says to treat the single electron on a radical as a region of electron density. The single electron would be less repulsive than two electrons in a lone pair and would effect bond angles less because of that. Still it would count as a single region of electron density.
