Problem: Write a hybridization and bonding scheme for each molecule. Label all bonds in NF3.

FREE Expert Solution

Step 1: Determine the central atom in this molecule.

• N less electronegative atom than F → central atom


Step 2: Calculate the total number of valence electrons present.          

NF3:

        Group               Valence Electrons

N         5A                   1 × 5 e = 5 e

F          7A                   3 × 7 e = 21 e

              Total:  26 valence e


Step 3: Draw the Lewis Structure for the molecule

  •  prefers to have 1 bond and complete octet
  • surround N with three F atoms
  • Distribute extra electrons in each of the F atoms (since they prefer to have complete octet)
  • if there are remaining electrons, place it in the central atom
     


Step 4: Determine the hybridization of the central atom.

  • There are 4 domains or groups around central element N:
  • 3 F atoms + 1 lone pair = 4 domains
  • It will need 4 orbitals to accommodate these 4 groups.

Orbitals that can be used by the central atom:

 Subshell                   Total # of orbitals 

        s           _                1 orbital  

        p       _ _ _              3 orbitals

        d        _ _ _ _ _        5 orbitals

  • 1 s orbital + 3 p orbitals = 4 orbitals (4 groups)
