Question

Compare $Li$ and $Be$ according to the polarisation of cations :

• A. $L{i}^{+}<B{e}^{2+}$
• B. $L{i}^{+}>B{e}^{2+}$
• C. $L{i}^{+}=B{e}^{2+}$
• D. None of these

Answer 1

The correct option is A $L{i}^{+}<B{e}^{2+}$

As the charge on the ion increases and size decreases polarization incresases,so the correct order of polarization $L{i}^{+}<B{e}^{2+}$
Hence option A is correct.
