Arrange the following cations based on conductivity in aqueous solution:
Li+ (I), Na+ (II), K+ (III), Cs+(IV)
I>II>III>IV
IV>III>II>I
IV>I>III>II
IV>III>I>II
Cs+ is least hydrated and moves faster in aqueous solution but as we up in the group the hydration is increased, increasing the radius, and decreasing the mobility of the cation.
