### Hybridization

Is a trigonal planar considered sp^3d?

### Re: Hybridization

it depends! hybridization is mainly talking about electron arrangement on the central atom (which includes both lone pairs and bonding pairs) so there are different shapes depending on the amount of lone pairs and bonding pair

### Re: Hybridization

A trigonal planar molecule has 3 regions of electron density. the regions of electron density is equal to the number of hybrid orbitals. Therefore a trigonal planar molecule has a hybridization of sp2 (a hybrid of 1 s orbital and 2 p orbitals).

### Re: Hybridization

The VSPER formula for trigonal planar is AX3. Because it has 3 regions of electron density, it has a hybridization of sp2. If a molecule has 2 regions of electron density it will have a hybridization of sp, 3 = sp2, 4=sp3, 5=sp3d, 6=sp3d2.

### Re: Hybridization

The hybridization orbital of a trigonal planar is sp^2 since it has three regions of electron density. A trigonal pyramidal would have a hybridization of sp3 since it has four regions of electron densities.

### Re: Hybridization

trigonal planar is sp2 since it has 3 electron densities, while tetrahedral would be sp3 since it has 4 electron densities.

### Re: Hybridization

Trigonal planar has 3 regions of electron density so it would be sp2

### Re: Hybridization

Trigonal planar is just one possible molecular structure of sp3d. Actually, the specific structure varies depending on the number of bonding regions and nonbonding regions (or lone pairs). I recommend you to memorize the table of hybridization on textbooks.

Hope this helps!

### Re: Hybridization

In terms of electron geometry, sp3d generally corresponds with the trigonal bipyramidal shape, which has a VSEPR formula of AX5. It can definitely differ with regards to molecular geometry though, as stated by the prior answers. Nonetheless, sp3d hybridization indicates that five hybrid orbitals are needed for five electron domains around the central atom.

Trigonal planar is considered sp^2 hybridization because it has 3 regions of electron density.
