Coefficients for hybridization

[Aurbal Popal]

During the lecture, most of the hybridizations had coefficients as well as the hybridization. For example, a bond between carbon atoms might have a hybridization of 2sp² but usually in the textbook they just ask for the sp² part. When is it necessary to add a two in front of it?

[Atul Saha 3D]

That coefficient juts gives the primary quantum number. But the hybridized orbital type is sp2 or sp3 and just like a "normal" s or p orbital can theoretically be found at any principal quantum number.

[Alana Sur 3B]

I've noticed that the TAs don't put the principal quantum number when the question just asks for the hybridization but they use it when the question is about describing a bond (eg. - sigma(C 2sp3 - H 1s)
