Solution

The correct option is D $- 0.24 V$
$O C l^{-} + H_{2} O + e^{-} \to C l^{-} + 2 O H^{-} E_{r e d}^{\circ} = 0.86 V$
$C l^{-} \to \frac{1}{2} C l_{2} + e^{-} - ------------------ - E_{o x i .}^{\circ} = - 1.10 V$
$O C l^{-} + H_{2} O \to \frac{1}{2} C l_{2} + 2 O H^{-} - -------------------------------- - E^{\circ} = 0.86 + (- 1.10)$
$= - 0.24 V$ .
