Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Write the molecular formula.
Hypochlorous acid has the formula \(\mathrm{HOCl}\).
Step 2: Assign known oxidation states.
Hydrogen generally has an oxidation state of \(+1\) and oxygen has an oxidation state of \(-2\).
Step 3: Calculate oxidation state of chlorine.
Let the oxidation state of chlorine be \(x\). Then:
\[ (+1) + x + (-2) = 0 \] \[ x = +1 \]
Step 4: Conclusion.
Thus, the oxidation state of chlorine in hypochlorous acid is \(+1\).
Hypochlorous acid has the formula \(\mathrm{HOCl}\).
Step 2: Assign known oxidation states.
Hydrogen generally has an oxidation state of \(+1\) and oxygen has an oxidation state of \(-2\).
Step 3: Calculate oxidation state of chlorine.
