The stability of the following alkali metal chlorides follows the order:

`LiCl gt KCl gt NaCl gt CsCl`

`CsCl gt KCl gt NaCl gt LiCl`

`NaCl gt KCl gt LiCl gt CsCl`

`KCl gt CsCl gt NaCl gt LiCl`

Text Solution

Verified by Experts

The correct Answer is:

Stability of a compound depends upon its enthalpy of formation `DeltaH_(f)` The more negative value of `DeltaH_(f)` shows more stability of a compound. Thus KCl is more stable than `LiCl,`
`DeltaH_(f)" for "LiCl=-"408 kJ/mol"`
`DeltaH_(f)" for "KCl=-"436 kJ/mol"`
