The correct order of electrical conductivity of alkali metals ions in their aqueous solution for 
and 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
As we move down the group, the atomic and ionic size of alkali meta's increases. As the size increases, the extent of hydration decreases in aqueous solution. The electrical conductivity or ionic mobility is inversely proportional to extent of hydration. So, extent of hydration 
. Hence, the increasing order of electrical conductivity of alkali metals ions in their aqueous solution is
