2.45 (7th ed)

Postby Duby3L » Sat Nov 24, 2018 1:18 am

How come when writing the hybridization for a sigma bond between oxygen and carbon we use the notation (C2sp2,O2sp2), but when we write the notation for the oxygen lone pair we do not include the 2--which refers to oxygen being in the second row--and simply write (Osp2) for the lone pair? So, why do omit the 2 when writing it for a lone pair but not for a sigma or pi bond?

I am guessing since the lone pairs are not part of a sigma or a pi bond, the 2 is not included in the notation. There might not be a need for the distinguishment for the second row when there are no bonds with lone pairs.
