Question

Assertion :In organic layer test, $C{l}_2$ water is added to the sodium extract, which oxidises $B{r}^{⊝}$ and $I^{⊝}$ ions to $B{r}^{⊝}$ and $I_2$ respectively Reason: Reduction potential of $C{l}_2$ is greater than that of $B{r}_2$ and $I_2$

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

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

Reactions:
$C{l}_2+B{r}^{⊝}⟶2C{l}^{⊝}+B{r}_2$
$C{l}_2+I^{⊝}⟶2C{l}^{⊝}+I_2$
Reduction potential $\left(E^{o}C{l}_2/C{l}^{⊝}\right)>E^{o}B{r}_2/B{r}^{⊝}$ or $E^o{I}_2/I^{⊝}$
