Aluminum Chloride and Chloride Ion (Lewis Acid-Base)

AlCl3 + Cl− → AlCl4−

Tổng quan

Aluminum chloride acts as a Lewis acid, accepting a lone pair from chloride ion to form the tetrachloroaluminate anion. AlCl₃ has an electron-deficient aluminum center that readily accepts electron pairs. This Lewis acidity makes AlCl₃ one of the most important catalysts in organic chemistry.
