Assertion : In organic layer test, `Cl_(2)` water is added to the sodium extract, which oxidises which oxidises `Br^(Theta) and I^(Theta)` ions to `Br_(2)` and `I_(2)`, respectively.
Reason : Reduction potential of `Cl_(2)` is greater than that of `Br_(2)` and `I_(2)`.

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

Answer

A

Explanation

`Cl_(2)+Br^(Theta)rarr2Cl^(Theta)+Br_(2),Cl_(2)+I^(Theta)rarr2Cl^(Theta)+I_(2)`
Reduction potential `E_((Cl_(2)Cl^(-)))^(@)gtE_((Br_(2)//Br^(-)))^(@)orE_((I_(2)//I^(-)))^(@)`.
