Which of the following option is correct about the displacement reaction? In this reaction, one element can displace the other element. Low reactive element can not displace the high reactive element.

Which of the following option is correct about the displacement reaction? In this reaction, one element can displace the other element. Low reactive element can not displace the high reactive element. Correct Answer Both are correct

The correct answer is 3 i.e. Both are correct.

Displacement reactions:

  • Those reactions in which one element takes the place of another element in a compound, are known as displacement reaction.
  • In general, a more reactive element displaces a less reactive element from its compound.
  • In the given reaction, magnesium displaces copper from copper sulfate solution.
  • The blue color of copper sulfate solution fades due to the formation of a colorless solution of magnesium sulfate.
  • A red-brown deposit of copper metal is formed on the magnesium piece.
  • Magnesium can displace copper from the copper sulfate solution because magnesium is more reactive than copper.
    • ​CuSO4 + Mg → MgSO4​ + Cu

Given below are two statements, one labelled as Assertion (A) and the other as Reason (R). Assertion (A): Barani writes, ‘Sultan Muhammad Tughlaq talked as if he hated low-born people more than he hated idols, Nevertheless, I have seen him promoting Najba, the low-born son of a musician, to such an extent that he rose higher in status than many maliks, for Gujarat, Multan and Badaon were put in his charge . . . It was strange how he gave high offices and governments of extensive territories and great provinces to men of low and mean birth’. Reason (R): The Sultan believed in offices being open to talent. He dispensed with whatever considerations of birth had persisted in the administration and appointed low-born persons to the highest offices in the administration. In the context of the above two statements which of the following is correct ?
