Answer:

The hybrid # sp^3# orbital

Explanation:

Carbon has four valance orbitals 1 s and 3 p s
In the ground state the electron configuration is #1s^2 2s^2 2p^2#

In the ground state Carbon can only form 2 bonds as in Carbon monoxide. # CO# To form 4 bonds as in Carbon tetrachloride #C Cll_4# Carbon has to blend all four orbitals the 1 s and 3 p s. This forms four equal # sp^3# tetrahedral orbitals. Each of the Cl atoms forms a sigma bond with one of these four equal hybridized orbitals.
