Questions & Step-by-Step Solutions

What is the hybridization of the central atom in BF3?
  • Step 1: Identify the central atom in BF3, which is boron (B).
  • Step 2: Count the number of bonds boron forms with fluorine atoms. In BF3, boron forms three bonds with three fluorine atoms.
  • Step 3: Determine the number of electron groups around the boron atom. Since there are three bonds and no lone pairs, there are three electron groups.
  • Step 4: Use the number of electron groups to find the hybridization. Three electron groups correspond to sp2 hybridization.
  • Step 5: Understand that sp2 hybridization means the bonds are arranged in a trigonal planar shape.
