Consider a molecule of phosphoric acid, H3PO4, which is commonly found in soft drinks and fertilizers. In this molecule, phosphorous is the central atom bonded to four oxygen atoms. Three of these oxygen atoms are each connected to one hydrogen atom, while the fourth oxygen atom is involved in a double bond with phosphorous. The molecular structure of phosphoric acid leads to a specific arrangement of the electron clouds around these bonds.
Given the molecular structure described, what type of hybridization does the phosphorus atom undergo?
