The correct order of hydration enthalpies of alkali metal ions is :
 

  • Option 1)

    Li^{+}>Na^{+}+K^{+}>Cs^{+}>Rb^{+}

     

  • Option 2)

    Li^{+}>Na^{+}+K^{+}>Rb^{+}>Cs^{+}

  • Option 3)

    Na^{+}>Li^{+}+K^{+}>Rb^{+}>Cs^{+}

     

  • Option 4)

    Na^{+}>Li^{+}+K^{+}>Cs^{+}>Rb^{+}

 

Answers (1)

Hydration \; energy\prec \frac{Charge}{Size}

\therefore  Li^{+}>Na^{+}+K^{+}>Rb^{+}>Cs^{+}

Less size more Hydration energy.

 


Option 1)

Li^{+}>Na^{+}+K^{+}>Cs^{+}>Rb^{+}

 

Option 2)

Li^{+}>Na^{+}+K^{+}>Rb^{+}>Cs^{+}

Option 3)

Na^{+}>Li^{+}+K^{+}>Rb^{+}>Cs^{+}

 

Option 4)

Na^{+}>Li^{+}+K^{+}>Cs^{+}>Rb^{+}
