What is the trend of solubility, thermal stability and basic character of hydroxides fo alkaline earth metals ?

A

`(1)` and `(2)` only

B

`(1)` and `(3)` only

C

`(1),(2)` and `(3)`

D

None

Text Solution

Verified by Experts

The correct Answer is:
4
`(1)` The solubility increases down the group because the change in lattice energy is more as compared to hydration energy. Thermal stability and the basic character both increases down the group as metallic character increases.
`(2)` It is correct statement.
`(3)` Beryllium and aluminium are diagonally related. Chlorides of both are covalent in nature and thus are soluble in organic solvents. Chlorides of both are electron deficient and thus act as strong Lewis acids.
