Vedclass · Answer

(D) redox reaction is one in which the oxidation state of at least one element changes.In option $(A)$,$Rb$ goes from $0$ to $+1$ and $H$ goes from $+1$ to $0$.In option $(B)$,$Cu$ goes from $+2$ to $+1$ and $I$ goes from $-1$ to $0$.In option $(C)$,$O$ in $H_2O_2$ goes from $-1$ to $-2$ (in $H_2O$) and $0$ (in $O_2$).In option $(D)$,$4KCN + Fe(CN)_2 	o K_4Fe(CN)_6$ is a complex formation reaction where the oxidation states of all elements remain unchanged $(K=+1, C=+2, N=-3, Fe=+2)$.Therefore,$(D)$ is not a redox reaction.
