Chapter 16, Problem 125QP

Identity the Lewis acid and the Lewis base in the following reactions:

(a)

${\text{AlBr}}_{\text{3}}\left(s\right){\text{ + Br}}^{\text{-}}\left(aq\right)\to {\text{AlB}}_4^{-}\left(aq\right)$

(b)

$6\text{CO}\left(g\right)\text{ + Cr}\left(s\right)\to \text{Cr}{\left(\text{CO}\right)}_6\left(s\right)$

(c)

${\text{Cu}}^{\text{2+}}\left(aq\right){\text{ + 4CN}}^{\text{-}}\left(aq\right)\to \text{Cu}{\left(\text{CN}\right)}_4^{2-}\left(aq\right)$
