# How many sigma and pi bonds do sp, sp2, sp3, sp3d, sp3d2 have?

##### 1 Answer

Without knowing more context, it's not possible to know the number of

If you want to get the number of

One pure double bond has one

From knowing the hybridization of the central atom, we can determine the number of

Examples:

#sp# hybridization in acetylene corresponds withtwo#sigma# bonds around one carbon.

#sp^2# hybridization in ethene corresponds withthree#sigma# bonds around one carbon.

#sp^3# hybridization in methane corresponds withfour#sigma# bonds around one carbon.

#sp^3d# hybridization in#"PF"_5# corresponds withfive#sigma# bonds around one phosphorus.

#sp^3d^2# hybridization in#"SF"_6# corresponds withsix#sigma# bonds around one sulfur.

You can see that the number of orbitals used in the hybridization spits out the same number of hybridized orbitals that can

Therefore, the **number of orbitals used** in the hybridization is the **number of** **bonds made** around the central atom.
