Which of the following is not true?

Options

A. Group 2 elements are electropositive, strong reducing agents but not as strong as group 1 elements.
B. The reducing power of groups 2 elements increases down the group.
C. Be has got the most negative standard reduction potential.
D. The magnesium cation is more easily reduced than the cations of the heavier members of the group.

Answer

C

Explanation

`E^(@)(Be^(2+)//Be)` is the least negative of all group 2 elemetns' potential on account of relatively large value of the enthlapy of atomization and ionization enthalpies `(Delta_(i)H_(1)+Delta_(i)H_(2))` of the metal.
