Consider the following statements and pick out the wrong one.
(1)The solubility, thermal stability and the basic character of the hydroxides of alkaline earth metals increases from`Mg(OH)_2` to `Ba(OH)_2`
(2)The dehydration of hydrated chlorides, bromides and iodides of Ca,Sr and Ba can be achieved on heating.
(3)The chlorides of both beryllium and aluminium are soluble in organic solvents and are strong lewis acids.

Options

A. (1) and (2) only
B. (1) and (3) only
C. (1),(2) and (3) only
D. None

Explanation

To solve the question, we need to evaluate the three statements provided and determine which one is incorrect.

### Step 1: Analyze Statement 1
**Statement 1:** The solubility, thermal stability, and the basic character of the hydroxides of alkaline earth metals increase from `Mg(OH)₂` to `Ba(OH)₂`.

- **Solubility:** As we move down the group from magnesium to barium, the ionic size increases, leading to a decrease in lattice energy. The hydration energy also decreases, but the decrease in lattice energy is more significant, resulting in increased solubility of hydroxides.

- **Thermal Stability:** The thermal stability of hydroxides increases down the group. This is because the larger ionic size of barium leads to lower lattice enthalpy, which correlates with higher thermal stability.

- **Basic Character:** The basic character of hydroxides increases down the group due to lower ionization energy and increased metallic character, making it easier for the hydroxide to dissociate into OH⁻ ions.

**Conclusion for Statement 1:** This statement is correct.

### Step 2: Analyze Statement 2
**Statement 2:** The dehydration of hydrated chlorides, bromides, and iodides of Ca, Sr, and Ba can be achieved on heating.

- The halides of calcium, strontium, and barium are known to be hygroscopic and can lose water upon heating. For example, calcium chloride (CaCl₂·xH₂O) can dehydrate to form anhydrous CaCl₂.

**Conclusion for Statement 2:** This statement is also correct.

### Step 3: Analyze Statement 3
**Statement 3:** The chlorides of both beryllium and aluminum are soluble in organic solvents and are strong Lewis acids.

- Beryllium and aluminum chlorides are indeed covalent and can dissolve in organic solvents. They are also electron-deficient, which allows them to act as strong Lewis acids.

**Conclusion for Statement 3:** This statement is correct as well.

### Final Conclusion
Since all three statements are correct, there is no wrong statement among the options provided. Therefore, the answer to the question is that none of the statements are incorrect.

### Answer: None of the statements are wrong.
