Most of the metals react chemically with other substances in one form or another. Few metals which do not react with common chemicals are called noble metals e.g., silver, gold, platinum. The rate of reaction with which metals react is not same for all the metals. The rate of reaction depends on the reactivity of metals. On the basis of their reactive nature, a series known as reactivity series has been drawn in which metals are arranged in decreasing order of their reactivity.

Observe the table given below:

= reaction takes place
= reaction does not take place
Identify the correct order of reactivity of the given metals.

Options

A. `X lt Z lt Y`
B. ` Z lt X lt Y`
C. `X gt Z gt Y`
D. `Y lt X lt W`

Answer

C

Explanation

X is most reactive as it displaces all ions while Y is least reactive. Z can displace Y but not Whence the order is, X > W > Z > Y.
