Account for the following observations. $$AlCl_{3}$$ is a Lewis acid.

As we know mostly electron-deficient species are known as Lewis acids and these species have vacant orbitals. In case of $$AlCl_3$$,$$Al$$ has only six electrons in its valence shell.Thus, it is electron-deficient species and has a tendency to accept an electron. Therefore, act as Lewis acid.
