Q. The standard $E_{red}^{{^\circ}}$ values of A, B and C are +0.68 V, - 2.54 V, - 0.50 V respectively. The order of their reducing power is

A) $A\ > \ B\ > \ C$
B) $A\ > \ C\ > \ B$
C) $C\ > \ B\ > \ A$
D) $B\ > \ C\ > \ A$
Explanation

(d)
Reducing character is based upon higher negative value of reduction electrode potential.
Thus , order of reducing character is
$B\ > \ C\ > \ A$
