Q.

Chlorine undergoes disproportionation in alkaline medium as shown below:

aCl2(g)+bOH(aq)-cClO(aq)-+dCl(aq)-+eH2O(l)

The values of a, b, c and d in a balanced redox reaction are respectively:

1 2, 2, 1 and 3  
2 1, 2, 1 and 1  
3 2, 4, 1 and 3  
4 3, 4, 4 and 2  

Ans.

(2)        

C0l2(g)+2OH-(aq)Cl-(aq)+Cl+1O-(aq)+H2O(l)

a = 1, b = 2, c = 1, d = 1
