Question

Assertion: $B{r}_2$ and $I_2$ cannot oxidize $C{l}_2$.

Reason: $C{l}_2$ has a reduction potential higher than that of $B{r}_2$ and $I_2$.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

Oxidation is the loss of electrons. Chlorine has the ability to take electrons from both bromide ions and iodide ions. Bromine and iodine can't get those electrons back from the chloride ions formed. That means that chlorine is a more powerful oxidising agent than either bromine or iodine as the reduction potential of $C{l}_2$ is higher than that of $B{r}_2$ and $I_2$.
