Vedclass · Answer

(C) Lewis acid is an electron pair acceptor,and a Lewis base is an electron pair donor. $CO_2 + H_2O \rightarrow H_2CO_3$ is a Lewis acid-base reaction. $AlCl_3 + Cl^- \rightarrow [AlCl_4]^-$ is a Lewis acid-base reaction. $B(OH)_3 + H_2O \rightarrow [B(OH)_4]^- + H^+$ is a Lewis acid-base reaction. In $SF_6$,the sulfur atom is already in its maximum oxidation state $(+6)$ and is sterically hindered by six fluorine atoms,making it chemically inert towards further reaction with $BF_3$. Thus,$SF_6 + BF_3$ does not undergo a Lewis acid-base reaction.
