Which among the following is not correct?

Options

A. If `E_(A^(n+)//A)^@` is negative, `H^+` will be reduced to `H_2` by the element A.
B. Compounds of (Zn, Na, Mg) are reduced by hydrogen `(H_2)` whereas those of noble metals (Cu, Ag, Au) are not reducible.
C. If `E_(A^(n+)//A)^@` is positive, `A^(n+)` will be reduced to A by `H_2` .
D. `M|M^(n+)||H^+||H_2(pt)` will be spontaneous if `E_(M^(n+)//M)^@` is negative.

Answer

B

Explanation

Reduction potential of hydrogen is greater than that of Zn, Na and Mg.
