Assertion : All halogens undergo disprop...

Assertion : All halogens undergo disproportionation reaction in alkaline medium.
Reason : All halogens exhibit variable oxidation states. If both (A) and (R) are correct and (R) is the correct explanation of (A)., If both (A) and (R) are correct, but (R) is not the correct explanation of (A)., If (A) is correct, but (R) is incorrect., If both (A) and (R) are incorrect.

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.

Text Solution

Verified by Experts

The correct Answer is:
D
`Cl_2, Br_2` and `I_2` undergo disproportionation reaction whereas fluorine shows departure being the most electronegative element. Fluorine cannot exhibit positive oxidation state and hence does not show disproportionation tendency.
