Question

Chlorine undergoes disproportionation in alkaline medium as shown below :

\(a\,Cl_2(g) +b\,OH^-(aq)\rightarrow c\,ClO^- (aq) +d\,Cl^-(aq)+e\,H_2O(l)\)

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

(1) 1, 2, 1 and 1 

(2) 2, 2, 1 and 3 

(3) 3, 4, 4 and 2 

(4) 2, 4, 1 and 3

Answer 1

(1) 1, 2, 1 and 1 

\(\Rightarrow Cl_2 +2 \overline {O}H \longrightarrow Cl^-+ClO^- +H_2O \)
