Vedclass · Answer

(C) According to Lewis acid-base theory,a Lewis acid is an electron pair acceptor. The acidity of a metal cation depends on its charge-to-size ratio (ionic potential). $Al^{3+}$ has a higher charge $(+3)$ and a smaller ionic radius compared to $Mg^{2+}$ $(+2)$. Therefore,$Al^{3+}$ has a higher charge density and is a stronger Lewis acid than $Mg^{2+}$. Conversely,$Mg^{2+}$ is a weaker Lewis acid than $Al^{3+}$.

$Mg^{2+}$ is . . . . . . than $Al^{3+}$.
