Out of the following compounds, how many possess a higher covalent character than ? , , , , , , , . — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Covalent character requires a cation with high polarizing power (small size, high charge, or pseudo-inert gas configuration). Cations smaller or more highly charged than $Na^+$ are $Li^+, Mg^{2+}, Al^{3+}$. Cations with a pseudo-inert gas configuration are $Cu^+, Ag^+$. The larger alkali metals ($K^+, Rb^+, Cs^+$) form more ionic chlorides. Total = 5 ($LiCl, CuCl, MgCl_2, AlCl_3, AgCl$).
