Problem: Use the formal charge arguments to rationalize why BF3 would not follow the octet rule.

FREE Expert Solution
  • Analyze the Lewis structure first then deduce how BF3 exists as neutral molecule 
  • Then compare this to the Lewis structures with formal charges but appears as neutral molecule
  • B will appear as the central atom since it is less electronegative than F
  • Boron has valence electron of 3 while F has 7. Total valence electron is 24. 3(1) + 7(3) = 24
  • F atoms will appear as having 3 lone pairs while being single bonded to B
