Q.

The alkaline earth metal nitrate that does not crystallize with water molecules, is:

  1. A

    Sr(NO3)2 

  2. B

    Mg(NO3)2

  3. C

    Ca(NO3)2 

  4. D

    Ba(NO3)2

Solution

Down the group as the charge density decreases so chances of formation of hydrate decreases. So, Ba(NO3) 2 does not crystallise with water molecules.
