The correct order of reduction potentials of the following pairs is...

The correct order of reduction potentials of the following pairs is

A. Cl2/Cl−{Cl}_{2} / {Cl}^{-}

B. I2/I−{I}_{2} / {I}^{-}

C. Ag+/Ag{Ag}^{+} / Ag

D. Na+/Na{Na}^{+} / Na

E. Li+/Li{Li}^{+} / Li

Choose the correct answer from the options given below.

Options

  1. AA>B>C>E>DA > B > C > E > D
  2. BA>C>B>E>DA > C > B > E > D
  3. CA>B>C>D>EA > B > C > D > E
  4. DA>C>B>D>EA > C > B > D > E

Correct answer

D. A>C>B>D>EA > C > B > D > E

Step-by-step solution

ECl2∣Cl−0=1.36E∘I2∣I−=0.54ELi+∣Li=−3.05E∘Ag+∣Ag=0.80ENa+∣Na=−2.71\begin{array}{ll}{E}_{{Cl}_{2} ∣ {Cl}^{-}}^{0} = 1 .36 \\ {E}^{∘}{I}_{2} ∣ {I}^{-} = 0 .54 \\ {E}_{{Li}^{+} | Li} = - 3 .05 \\ {E}^{∘}{Ag}^{+} ∣ Ag = 0 .80 \\ {E}_{{Na}^{+} | Na} = - 2 .71\end{array}

So, we can clearly see the order of reduction potential.

A>C>B>D>EA > C > B > D > E
