Determining Factors

Postby Courtney McHargue 1I » Fri Nov 30, 2018 2:23 pm

Is hybridization always based off of the number of bonds or lone pair electrons around the central atom or are there other factors that could affect it?

Hybridization is based on the number of electron densities around the atom, so a good rule to follow is that the number of regions of electron density equals the number of hybridization orbitals.

Hybridization is based on electron densities surround a certain atom, similar to how we view electron density arrangements of molecules, we take a single bond, double bond, triple bond or lone pair as 1 form of electronic density. In other words a triple bond is the same as a single bond in terms of electron density. For example im H2O the Hybridization of the central atom O is O2sp3 since it has 2 single bonds and 2 lone pairs of electrons attached to it. It has an electronic density of 4 (2 single bonds+2 lone pairs)

It is based on the number of electron domains (in 14A I think they’re called regions of electron densities, per the previous post!) :-)
Put simply, one electron domain/region of electron density can be:
- a lone pair
- bonds (multiple bonds are counted as one domain)

Please correct me if there’s any additions! Ty :-)
