The correct statement is

Options

  1. A( BF ₃ ) is the strongest Lewis acid among the other boron halides.
  2. B( BI ₃ ) is the weakest Lewis acid among the boron halides.
  3. CThere is maximum ( p -p_ ) back bonding in ( B F₃ )
  4. DThere is minimum ( p_ -p_ I ) back bonding in ( B F₃ )

Correct answer

C. There is maximum ( p -p_ ) back bonding in ( B F₃ )

Step-by-step solution

There is maximum ( p -p ) back bonding in ( B F₃ ) due to identical size of ( 2 p⁻ )orbitals of ( B ) and ( F )
