During the formation of chemical bonds, hybridization can occur. Atomic orbitals merge together mathematically to form hybrid orbitals. What hybrid orbitals are formed when one s orbital and three p orbitals all hybridize? (A) Four sp2 orbitals, (B) two sp2 orbitals, (C) four sp3 orbitals, (D) one sp3 orbital, (E) three sp3 orbitals.

As the question states, hybridization is when the mathematical functions described by the atomic orbitals are mixed together to form hybrid orbitals. These hybrid orbitals have new and different shapes. Say we have electrons in s and p orbitals. The hybridization process begins with one of the electrons in an s orbital getting promoted to an empty p orbital. These four unpaired electrons, one in the s orbital and three in the p orbital, will merge together to create four identical sp3 hybrid orbitals.

We can start off with a different number of unpaired electrons to create different kinds of hybrid orbitals. Unpaired electrons in 1s orbital and 2p orbitals will hybridize to give us three sp2 orbitals. And unpaired electrons in 1s and 1p orbital hybridize to give us two sp orbitals. This question asked us which hybrid orbitals are formed, when 1s and 3p orbitals hybridize. As we just saw, this will give us four sp3 orbitals, which is answer choice (C).
