lone pairs

[Moryel Yashar 1J]

Are lone pairs taken into consideration when determining the hybridization of a central atom?

[Nicholas Carpo 1L]

Yes the lone pairs are taken into account since the number of hybrid orbitals is equal to the number of regions of e- density around the atom.

[Yvonne Du]

Yes, one lone pair is considered as one electron density. Since hybridization is based on the number of electron density, you consider lone pairs too.

[Kavya Juwadi 3C]

One example of this would be the the molecule H^2O. The central atom, oxygen has two bonds ( one with each hydrogen ) and two sets of lones pairs. Therefore the hybridization of oxygen would sp^3.

[Tony Ong 3K]

yes lone pairs dictates the molecular shape.
For instance, let us assume that a central atom has a steric number of 4. This means that its electron arrangement is tetrahedral, however say it has 2 lone pairs. This means that the molecular shape is angular.

Anyhow, Have a nice night!!!

[Samantha Chang 2K]

Yes, a lone pair is considered a region of electron density and therefore you will count it to find hybridization.

[Eruchi Okpara 2E]

Is the answer automatically wrong if lone pairs are not separated from the shared pairs of electrons? for instance, if something has 3 shared pairs of electrons and 2 lone pairs, can it only be written as AX3E2 or can you write it as AX5?

The VSEPR formula calls to use A for the central atom, X for the bonded atoms, and E for the lone pairs of electrons. You can't write AX3E2 as AX5 because the shape of the molecules will be different.

[Abhi4F]

Yes, since lone pairs are a region of electron density it is taken into account for hybridization.

[Daniel Lai]

Lone pairs count as an area of electron density so they count for hybridization.

[leediane0916]

the lone pair counts as one electron density so you have to consider it!

[305127455]

Long pairs does count, and memorizing this and "formula" of hybridization should be enough to solve most of the related problems.

[905109118]

Yes the lone pairs are taken into consideration. The number of hybrid orbitals is equal to the number of regions around the atom.

[Divya Pimparkar 1E]

Yes, lone pairs are taken into account for hybridization because they are an electron region so they're used for placing electrons in hybrid orbitals

[Anand Narayan 1G]

Yes, Lone pairs do indeed count as an area of electron density, so yes, they count for hybridization.

[Anjali 4A]

To figure out hybridization, we need to calculate the steric number which is the number of sigma bonds and number of lone pairs, therefore do have to take lone pairs into account when figuring out the hybridization.

[Ricardo Martin 1J]

Yes, since hybridization relates to the # of areas of electron density and lone pairs are considered an area of electron density, then lone pairs are taken into consideration for hybridization.

[Jaifreen_Bhangu_3K]

Yes, you consider all regions of electron density.

[Jchellis 1I]

Lone pairs count just as much as an atom for a region of electron density

[josephperez_2C]

Each lone pair is considered a region of electron density so they should be taken into account.

[Jack Hewitt 2H]

Are lone pairs taken into consideration when determining the hybridization of a central atom?

Yes lone pairs are taken into consideration because they are still areas of electron density.
