Vedclass · Answer

(D) Lewis acid is a substance that can accept an electron pair.$BF_3$ has an incomplete octet (only $6$ electrons around $B$),so it acts as a Lewis acid.$SnCl_4$ has an empty $d$-orbital on the $Sn$ atom,allowing it to accept electron pairs,thus acting as a Lewis acid.$SnCl_2$ also has an incomplete octet and an empty $d$-orbital,enabling it to act as a Lewis acid.Therefore,all three species $BF_3, SnCl_2, SnCl_4$ act as Lewis acids.

Which of the following species among $BF_3, SnCl_2, SnCl_4$ act as Lewis acids?
