Solution

The correct option is A $A l N < M g O < N a F$
More the charge on the ions, more is the covalent character. Hence, the order of covalent charcter is $A l N > M g O > N a F$ . More is the covalent character, less is the solubility in water.
The order of solubility in water is $A l N < M g O < N a F$ .

Arrange the following in increasing order of solubility in H2O?NaF,MgO,AlN

The correct option is A AlN<MgO<NaFMore the charge on the ions, more is the covalent character. Hence, the order of covalent charcter is AlN>MgO>NaF. More is the covalent character, less is the solubility in water.The order of solubility in water is AlN<MgO<NaF.
