What type of orbital overlap is responsible for the π bond between carbon and oxygen in the molecule below?

According to picture below, p atomic orbitals overlap are responsible for the π bond between carbon and oxygen.
Both carbon and oxygen have sp2 hybridization in this carbonyl group. Carbon has three sigma bonds with sp2 orbitals and oxygen has one sigma bond with sp2 and two free electron pairs with sp2 orbitals. Pi bonds are formed between two p orbitals.

The overlap of the atomic orbitals depicts the relationship between the bond stability and strength. The pi bond overlap is because of the p atomic orbital.

What are pi bonds and hybridization?

Pi bonds are the bonds that involve the lobes of the two atomic orbitals that overlap with the orbit of the other atoms of the molecule or compound. It is generally the second bond present in the double-bonded atoms.

Between the atoms of the carbon and the hydrogen the p atomic orbital overlaps and results in the formation of the [tex]\rm sp_{2}[/tex] hybridization. The hybridization mixes and combines the two atomic orbitals to form another orbital.

The atom of the carbon contains three sigma bonds and oxygen contains one sigma bond. The p orbital of the atoms forms the pi bonds.

Therefore, p atomic orbital overlap forms the pi bond.
