Acidity of ( BF ₃ ) can be explained on the basis of which of the following concepts?

Options

  1. AArrhenius concept
  2. BBronsted-Lowry concept
  3. CLewis concept
  4. DBronsted-Lowry as well as Lewis concept

Correct answer

C. Lewis concept

Step-by-step solution

( B ) is ( BF ₃ ) is electron deficient i.e, lone-pair of electrons acceptor (Lewis acid), because in ( BF ₃ ), (B ) is (s p^2 ) hybridised and it does not satisfy octet ( ( B ) has say bonded electrons).
