Question

Ionic conductances of hydrated M + ions are in the order- (A) L i+(a q) > N a+(a q) > K+(a q) > R b+(a q) > C s+(a q) (B) Li +( aq ) > Na +( aq ) < K +( aq ) < Rb +( aq ) < Cs +( aq ) (C) L i+(A q) > N a+(a q) > K+(a q) > R b+(a q) < C s+(a q) (D) L i+(a q) < N a+(a q) < K+(a q) < R b+(a q) < C s+(a q)

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. Li +( aq. )< Na +( aq. )< K +( aq. )< Rb +( aq. )< Cs +( aq. )

Q. Ionic conductances of hydrated $M^{+}$ ions are in the order-

$L i^{+} (a q) > N a^{+} (a q) > K^{+} (a q) > R b^{+} (a q) > C s^{+} (a q)$

$L i^{+} (a q) > N a^{+} (a q) < K^{+} (a q) < R b^{+} (a q) < C s^{+} (a q)$

$L i^{+} (A q) > N a^{+} (a q) > K^{+} (a q) > R b^{+} (a q) < C s^{+} (a q)$

$L i^{+} (a q) < N a^{+} (a q) < K^{+} (a q) < R b^{+} (a q) < C s^{+} (a q)$

Due to high charge density of $L i^{+}$ is attracts more water molecules and becomes bulky so the ionic conductances of $M^{+}$ ions increase from $L i^{+}$ ion to $C s^{+}$ ion.

$L i^{+} ($ aq. $) < N a^{+} ($ aq. $) < K^{+} ($ aq. $) < R b^{+} ($ aq. $) < C s^{+} ($ aq. $)$

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

Li+(aq)>Na+(aq)>K+(aq)>Rb+(aq)>Cs+(aq)

Li+(aq)>Na+(aq)<K+(aq)<Rb+(aq)<Cs+(aq)

Li+(Aq)>Na+(aq)>K+(aq)>Rb+(aq)<Cs+(aq)

Li+(aq)<Na+(aq)<K+(aq)<Rb+(aq)<Cs+(aq)
