Following table represents the type of reactions of three metals with various solutions. Metal lron (II) Sulphate Copper (II) Sulphate Zinc Sulphate A No reaction Displacement Not known B No reaction No reaction No reaction C Displacement Not known No reaction Which of the following represents the correct order of reactivity of metals A, B, C Correct Answer C > A > B

Explanation:-

Chemical reaction: The chemical reaction is said to be the change that brings new products.

Displacement reaction: 

  • The reaction in which cation or anion from the reactant side is displaced to the products is called displacement reaction.
  • A displacement reaction is also known as a metal displacement reaction.
  • Metals of high reactivity displace the metals of low reactivity from their anions.

Double displacement reaction: The reaction in which both cation and anion is displaced to the products is called double displacement reaction.

Properties of Elements:

  • Zinc: Zinc is more reactive metal than Iron and copper.
  • Iron: Iron is least reactive than zinc but more than copper.
  • Copper: Copper is least reactive than zinc and iron.

Metal reactivity series:

The metals are arranged in increasing order of their reactivity which is known as the metal reactivity series.
