Question

which among the following is the correct order of reactivity series in their increasing order ? x-mercury , y-Lead , z-Iron

a)x<y>z
b)x<y<z
c)z<y>x
d)y>x>z​

Answer 1

Answer:

Correct option is

D

Fe<Zn<Mg<K

The reactivity series is a series in which metals are arranged in decreasing order of their reactivities.

Fe<Zn<Mg<K

In the reactivity series, the most active metal is at the top of the series.

Answer 2

Correct order of reactivity series in their increasing order is y>x>z

Pb > Fe > Hg Option (D)

Explanation:

Metals are arranged in decreasing order of the reactivities is Pb > Fe > Hg

In this reactivity series active metal is on the top of the series.

The arrangements of the metal in a vertical column in decreasing order is called reactivity series

Lead is more reactive than Iron

Mercury is less than in the given elements.

In reactivity series most reactive element is placed on the top of the series and the less at thebottom of the series.

Option (D) Correct order of reactivity series in their increasing order is y>x>z
