Acidity of \(\mathrm{BF}_3\) can be explained on the basis of which of the following concepts?
Acidity of \(\mathrm{BF}_3\) can be explained on the basis of which of the following concepts?
Arrhenius concept
Bronsted-Lowry concept
Lewis concept
Bronsted-Lowry as well as Lewis concept
Solution
\(\mathrm{B}\) is \(\mathrm{BF}_3\) is electron deficient i.e, lone-pair of electrons acceptor (Lewis acid), because in \(\mathrm{BF}_3\), \(B\) is \(s p^2\) hybridised and it does not satisfy octet ( \(\mathrm{B} \Rightarrow\) has say bonded electrons).
