NEET Chemistry The s-Block Elements Questions Solved


Ionic conductances of hydrated M+ ions are in the order-

(A) Li+aq>Na+aq>K+aq>Rb+aq>Cs+aq

(B) Li+aq>Na+aq<K+aq<Rb+aq<Cs+aq

(C) Li+aq>Na+aq>K+aq>Rb+aq<Cs+aq

(D) Li+aq<Na+aq<K+aq<Rb+aq<Cs+aq

(D). Due to high charge density of Li+ is attracts more water molecules and becomes bulky so the ionic conductances of M+ ions increase from Li+ ion to Cs+ ion.
