A molecule with the formula ab3 and a trigonal planar molecular geometry uses sp2 hybridization to form its σ bonds.
Trigonal hybridization is another name for sp2 hybridization. To create the new hybrid orbital known as sp2, one's orbital and two 'p' orbitals of equal energy are mixed together. Trigonal symmetry was used to generate a mixture of s and p orbitals, which are kept at 1200.
One s orbital and two p orbitals combine to generate three sp2 hybridizations, each of which has a 33 percent s character and a 67 percent p character. This process is known as sp2 hybridization. Anytime an atom is surrounded by three groups of electrons, this kind of sp2 hybridization is necessary.
Both the carbon and oxygen atoms are sp2 hybridized. The carbon atom can establish three bonds, one of which is to the oxygen, and possesses three sp2 hybridized orbitals.
