CHXI11:THE P-BLOCK ELEMENTS

316292 Among the following halogens, $F_{2}, {Cl}_{2}, {Br}_{2}$ and $I_{2}$ , which can undergo disproportionation reactions?

1 Only

I_{2}

2

{Cl}_{2}, {Br}_{2}

and

I_{2}

3

F_{2}

and

{Cl}_{2}

4

F_{2}, {Cl}_{2}

and

{Br}_{2}

Explanation:

$F_{2}$ cannot undergo disproportionation as it shows only $-$ 1 oxidation state and hence, has a tendency to reduce only. Remaining ${Cl}_{2}, {Br}_{2}, I_{2}$ can undergo disproportionation. So, the correct option is (2).
