Question

Which one of following chlorides has maximum tendency to form hydrate?
Bacl​2
​Mgcl​2
​Nacl
Licl

Answer 1

The correct option is Lithium chloride.  

Explanation:

• The reason is that lithium has the smallest size among many other ions.

• It is a polar molecule for water as it easily ionizes water.

• As a result of the water of crystallization, water molecules attach themselves with lithium.

• When lithium form the compound (LiCl.2H2O) it loses its polarising power.

• The size causes the polarizing power of molecule the greater the size the smaller will be the power.

Answer 2

LiCl = Lithium Chloride

so , option 4 is the correct answer
