Question

$CuCl$ has more covalent character than $NaCl$ because:

• A. ${Na}^{+}$ has more polarizing power than ${Cu}^{+}$
• B. ${Cu}^{+}$ has more polarizing power than ${Na}^{+}$
• C. ${Cl}^{-}$ has pseudo inert gas electron configuration
• D. ${Na}^{+}$ has pseudo inert gas electron configuration

Answer 1

Answer: (B)

${Cu}^{+}$ has more polarizing power than ${Na}^{+}$

CuCl has more covalent character than NaCl because $C{u}^{+}$ has more polarizing power than $N{a}^{+}$.
Higher is the polarizing power of the cation, higher is the covalent character.
