`C_(2)H_(5)OC_(2)H_(5)to underset("red color") underset(darr KCNS) underset( darr Fe^(2+)) (A+B)`
Which is not true for above reactions?

Options

A. (a) `A` & `B` are explosives
B. (b) If `A` & `B` are present in ether, then prior ot its use `A` & `B` must be removed from ether
C. (c) `A` & `B` can not be removed by adding conc. `H_(2)SO_(4)`
D. (d) When `A` & `B` are treated with `Fe^(2+)` followed by `KCNS`, no redox reaction is invelved.

Explanation

To determine which statement is not true regarding the reactions involving the compound \( C_2H_5OC_2H_5 \) (diethyl ether), we will analyze the reactions and the properties of the products formed.

### Step 1: Identify the Reaction Products
The compound \( C_2H_5OC_2H_5 \) can decompose to form peroxides and hydroperoxides. These products are known to be unstable and can lead to explosive reactions.

**Hint:** Consider the nature of ethers and their decomposition products.

### Step 2: Analyze the Properties of A and B
From the decomposition of diethyl ether, we can identify that:
- **A** and **B** are likely peroxides or hydroperoxides.
- These compounds are known to be explosive.

**Hint:** Recall the characteristics of peroxides and hydroperoxides.

### Step 3: Check the Statements
1. **Statement A**: Peroxides and hydroperoxides are explosives.
- This statement is true.

2. **Statement B**: Peroxides and hydroperoxides are present in ether.
- This statement is also true.

3. **Statement C**: They cannot be removed by concentrated \( H_2SO_4 \).
- This statement is true; they are inert to concentrated sulfuric acid.

4. **Statement D**: The reaction of A and B with \( Fe^{2+} \) followed by \( KCN \) does not involve a redox reaction.
- This statement is false; the reaction does involve a redox process where \( Fe^{2+} \) is oxidized to \( Fe^{3+} \).

**Hint:** Evaluate each statement based on the chemical behavior of the compounds involved.

### Step 4: Conclusion
The statement that is not true is **Statement D**, as it incorrectly claims that the reaction does not involve a redox process.

**Final Answer:** The incorrect statement is **D**.
