hybridization of lone pairs

Postby sarahsalama2E » Tue Dec 03, 2019 10:41 pm

I am a bit unclear on how to determine the hybridization of lone pairs in a given structure. For instance, in formic acid, I understand the hybridization of all the bonds, such as the C-H bond is sigma and is (H1S, C2SP2), but why is the lone pair on the oxygen that is in between the C and the H have hybridization of 2sp3? What does 2sp3 refer to? If someone could provide an explanation of how to find the hybridization of specifically lone pairs that would be very helpful thanks.

I believe that the hybridization of any region of electron density around the central atom can be described in terms of the central atom's hybridization. Oxygen is sp3 hybridized, so all bonds and lone pairs are also sp3 (lone pairs count as a region of electron density).

Hybridization applies to atoms not to bonds or lone pairs, this might be some source of the confusion not entirely sure though.
