Which orbitals on carbon are involved in the sp2 hybrid orbitals and which orbital is involved in ?? 2s, 2pz involved in hybridization and 2px involved in ? bonding. The 2s, 2px, 2py are involved in hybridization and 2pzis involved in ? bonding. 2s, 2px involved in hybridization and 2py involved in ? bonding. 2s, 2px, 2pz involved in hybridization and 2py involved in ? bonding

Explanation / Answer

We can create a set of sp2 hybrid orbitals on the carbon and oxygen atoms that lie in this plane by mixing the 2s, 2px and 2py orbitals on each atom.

There are four valence electrons on a neutral carbon atom. One of these electrons is placed in each of the three sp2 hybrid orbitals. The fourth electron is placed in the 2pz orbital that wasn't used during hybridization.

There are six valence electrons on a neutral oxygen atom. A pair of these electrons is placed in each of two of the sp2 hybrid orbitals. One electron is then placed in the sp2 hybrid orbital that points toward the carbon atom, and another is placed in the unhybridized 2pz orbital.

The electron in the 2pz orbital on the carbon atom then interacts with the electron in the 2pz orbital on the oxygen atom to form a second covalent bond between these atoms. This is called a pi (p) bond because its looks like a p orbital when viewed along the bond.

option B is correct
