A Lewis acid is a substance that can accept a pair of electrons (an electron-pair acceptor). In the given compounds:

(A) BaCl2 - This is not a Lewis acid. It is a metal halide, and metals generally do not act as Lewis acids in this context.

(B) AlCl3 - This is a Lewis acid. Aluminum has an incomplete octet and can accept a pair of electrons, making it an electron-pair acceptor.

(C) BCl3 - This is a Lewis acid. Boron has an incomplete octet and can accept a pair of electrons.

(D) SnCl4 - This is a Lewis acid. Tin (Sn) has empty d orbitals and can accept a pair of electrons.

So, the compound that is not a Lewis acid is (A) BaCl2.
