# Comparison Of Lewis Acidity

Which is a stronger Lewis Acid $\ce{AlCl_3}$ or $\ce{SiCl_4}$?

I am confused as in $\ce{AlCl_3}$ , Al has an incomplete octet so it must be a stronger Lewis acid as compared to $\ce{SiCl_4}$, but the answer is just opposite.

• Well, answer is wrong so I guess there was a mistake or you misunderstood sth. – Mithoron Aug 11 '16 at 20:04
• agree, AlCl3 is much certainly a stronger Lewis acid. – orthocresol Sep 11 '16 at 4:24
