Questions & Step-by-Step Solutions

What is the hybridization of the phosphorus atom in PCl5?
Correct Answer: d2sp3
  • Step 1: Identify the central atom in PCl5, which is phosphorus (P).
  • Step 2: Count the number of chlorine (Cl) atoms bonded to phosphorus. There are 5 Cl atoms.
  • Step 3: Determine the number of electron pairs around phosphorus. Each Cl atom forms one bond, so there are 5 bonding pairs.
  • Step 4: Recognize that phosphorus can use its d orbitals for hybridization because it is in the third period of the periodic table.
  • Step 5: Combine the bonding pairs with the available orbitals: 1 s orbital, 3 p orbitals, and 2 d orbitals (d2sp3).
  • Step 6: Conclude that the hybridization of phosphorus in PCl5 is d2sp3.
