Question

Which of the following statements is correct about
the given reaction?
AB + C - CB + A
(1) B is more reactive than C
(2) C is more reactive than A
(3) B and A are inert gases
(4) A is a metallic ion

Answer 1

Answer:

2

Explanation:

(2) C is more reactive than A

Answer 2

C is more reactive than A is the correct statement about the given reaction.

Explanation:

1. The correct choice of the asked question is Option (2)

2. Here the reaction which is given is a reaction called or known as displacement reaction. In this type of reaction, the metal which is more reactive displaces the metal which is less reactive.

3. In the reaction given, we can clearly see that the metal C has displaced the metal A. After displacing, the metal C has formed bond with metal B and has formed a molecule.

4. So, it's possible only when C is more reactive. Thus, we can conclude that C is more reactive than metal A as C has displaced A and has formed bond with the metal B.

5. For example: When chlorine is added to a solution of sodium bromide, then we can observe that chlorine displaces the bromide of sodium bromide and forms new molecule called sodium chloride.
