Assertion (A): ICl on hydrolysis gives HI and HOCl.
Reason (R ): Water can attack iodine more readily.

Options

A. If both `(A)` and ` (R )` are correct and `(R )` is the correct explanation of `(A ) ` .
B. If both `(A)` and ` (R )` are correct and `(R )` is not the correct explanation of `(A )`
C. If`(A)` is correct, but `( R )` is incorrect .
D. Both `(A)` and `(R ) ` are incorrect .

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understanding the Assertion
The assertion states that "ICl on hydrolysis gives HI and HOCl." We need to evaluate if this statement is true or false.

- When ICl (iodine monochloride) undergoes hydrolysis, it reacts with water (H2O).
- The expected products of this reaction can be determined by considering the behavior of ICl in the presence of water.

### Step 2: Analyzing the Hydrolysis Reaction
The hydrolysis of ICl can be represented as follows:

\[ \text{ICl} + \text{H}_2\text{O} \rightarrow \text{HOI} + \text{HCl} \]

- In this reaction, iodine (I) is attacked by the hydroxyl ion (OH⁻) from water, while chlorine (Cl) is attacked by the hydrogen ion (H⁺).
- The products formed are HOI (hypoiodous acid) and HCl (hydrochloric acid).

### Step 3: Conclusion on the Assertion
Since the products of the hydrolysis of ICl are HOI and HCl, and not HI and HOCl as stated in the assertion, we conclude that:

- **Assertion (A) is false.**

### Step 4: Understanding the Reason
The reason states that "Water can attack iodine more readily." We need to evaluate if this statement is true or false.

- Iodine is more electropositive compared to chlorine, which means it has a weaker bond with chlorine in ICl.
- This makes iodine more susceptible to attack by nucleophiles, such as the hydroxyl ion from water.

### Step 5: Conclusion on the Reason
Given that iodine is indeed more reactive and can be attacked more readily by water, we conclude that:

- **Reason (R) is true.**

### Final Conclusion
- **Assertion (A) is false.**
- **Reason (R) is true.**

Thus, the answer to the question is that the assertion is wrong and the reason is correct.
