Solution

The correct option is B
It does not compare the relative reactivity of metals.

The series in which elements are arranged in order of their reactivity is known as an electrochemical series. Above hydrogen the more reactive elements are placed and the least reactive metals are placed below it. In short, this series compares the relative reactivity of metals.

Q. Hydrogen is not a metal-but it has been assigned a place in the reactivity series of metals. Give the reason for it.

Electrochemical series is a series of elements arranged in increasing order of their reduction potential and $E_{H^{+} / H_{2}}^{0} = 0$ . The metals above $H_{2}$ have – ve reduction potential, they are more reactive than hydrogen whereas metals below hydrogen are less reactive than $H_{2}$ . Reduction potential of metal depends upon
(i) sublimation energy (ii) ionization energy and (iii) hydration energy of ions.
