1.	The ionic conductance of the following cations in a given concentration is in the orderA. `Li^(+)ltNa^(+)ltK^(+)ltRb^(+)`B. `Li^(+)gtNa^(+)gtK^(+)gtRb^(+)`C. `Li^(+)ltNa^(+)gtK^(+)gtRb^(+)`D. `Li^(+)=Na^(+)ltK^(+)ltRb^(+)`
Answer» Correct Answer - A Due to extensive hydration of smaller alkali metal cations, the ionic radii is in the order `Li^(+)gtNa^(+)gtK^(+)gtRb^(+)` As such mobility in water is in the order `Li^(+)ltNa^(+)ltK^(+)ltRb^(+)`
