Question

Compare $L{i}^{+}$ and $B{e}^{+}$ in ionic conductance.

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

Answer 1

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

As smaller the size of the ion, larger will be the charge of the ion. Hence, greater the hydration and smaller ionic conductance of the ion. As $B{e}^{+}$ has less size, therefore has less ionic conductance than $L{i}^{+}$. So, the order is $B{e}^{+}<L{i}^{+}$.
Hence, option B is the correct answer.
