Aluminum chloride as a solid is not a strong Lewis acid

WebMar 8, 2024 · My attempt: In $\ce{BCl3}$ backbonding takes place and there is $\mathrm{3pπ-2pπ}$ overlap, and in $\ce{AlCl3}$ there is $\mathrm{3pπ-3dπ}$ overlap which is less effective than the first. So $\ce{Al}$ is more electron deficient as compared to $\ce{B}$ hence $\ce{AlCl3}$ must have higher Lewis acid character. But the answer is … WebThe Lewis diagram for AlCl3 is: The electron-pair geometry around the Al atom in AlCl3 is There are lone pair (s) around the central atom, so the geometry of AICIz is B. The Lewis diagram for Bel, is: i–Be-: The electron-pair geometry around the Be atom in Bel, is There are lone pair (s) around the central atom, so the geometry of Belz is A. WebThermal stability varies greatly for the series AlF3 (Melting point = 1291 Celcius), AlCl3 (Tsub = 180 Celsius), AlBr3 (Melting point = 97.5 C) and AlI3 (Melting point = 189.4 C). How can this be explained on the basis of crystal structure / molecular structure and chemical bonding conditions (see structure sketches below)?
