The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that `Cl2` (chlorine gas) reacts with cold and dilute `NaOH` (sodium hydroxide) to produce `NaClO3` (sodium chlorate). - In reality, when `Cl2` reacts with cold and dilute `NaOH`, the products formed are sodium chloride (`NaCl`) and sodium hypochlorite (`NaOCl`), along with water. Therefore, the assertion is **false**. 2. **Understanding the Reason (R)**: - The reason states that `Cl2` gets oxidized only in this reaction. - In the reaction with cold and dilute `NaOH`, chlorine undergoes both oxidation and reduction. It is reduced to `NaCl` (where chlorine is in the -1 oxidation state) and oxidized to `NaOCl` (where chlorine is in the +1 oxidation state). This means that chlorine is not only oxidized but also reduced in this reaction. Thus, the reason is also **false**. 3. **Conclusion**: - Since both the assertion and the reason are false, the correct option would be the one that states both are false. ### Final Answer: The correct option is **4**: Both assertion and reason are false.
