How many of the following are correctly matched :

Hydration energy : Li + > Na + > K + > Rb + > Cs +

Mobility of ions (aq) : Li + > Na + > K + > Rb + > Cs +

Density : Li < Na < K < Rb < Cs

Reaction with N 2 : Li < Na < Rb < Cs < K

Reducing nature of gas phase : Li < Na < K < Rb < Cs

Reducing nature in aq. phase : Li > Na > K > Rb > Cs

Text Solution

Verified by Experts

The correct answer is:

(2)

Hydration energy : Li + > Na + > K + > Rb + > Cs +

Mobility of ions (aq) : Li + < Na + < K + < Rb + < Cs +

Density : Li < K < Na < Rb < Cs

Reaction with N 2 : Li > Na > K > Rb > Cs

Reducing nature of gas phase : Li < Na < K < Rb < Cs

Reducing nature in aq. phase : Li > Cs > Rb > K > Na
