Question

Correct statement about chemical displacement is,
a. less reactive element displaces more reactive element
b. a non-metal displaces more reactive non metal
c. more reactive element displaces less reactive element
d. evolution of heat when carbon is burnt in air

Answer 1

Option C is Correct.

More reactive element displaces less reactive element.

Answer 2

The correct answer is more reactive element displaces a less reactive element, i.e., option c.

This is because a stronger reactive element is a weaker oxidising agent or more so a stronger reducing agent.

Thus, it displaces a less reactive element.

For example; M^(+2) + N = M + N^(+2). In this equation, electrode potential of N should be lesser than M to displace it.
