Which is Lewis acid?

Question

Which is Lewis acid? (A)  B F 3  (B)  N F 3  (C)  C l -  (D)  H2 O

Tardigrade Admin · Accepted Answer

Electron acceptors are Lewis acids. They are electron deficient compounds. BF 3 is Lewis acid because B has only 6 electrons in its valence shell and it can accept electrons. NF 3, Cl - and H 2 O have lone pair of electrons. Thus, they are electron donors and Lewis bases.
