MCQ
Two statements are given$-$ one labelled Assertion $(A)$ and the other labelled Reason $(R).$ Select the correct answer to these questions from the codes $\text{(a), (b), (c)}$ and $(d)$ as given below:
Assertion $(A):\ $ Linkage isomerism arises in coordination compounds because of ambidentate ligand.
Reason $(R):\ $ Ambidentate ligand like $NO_2$ has two different donor atoms i.e., $N$ and $O.$
  • Both Assertion $(A)$ and Reason $(R)$ are correct statements, and Reason $(R)$ is the correct explanation of the Assertion $(A).$
  • B
    Both Assertion $(A)$ and Reason $(R)$ are correct statements, but Reason $(R)$ is not the correct explanation of the Assertion $(A).$
  • C
    Assertion $(A)$ is correct, but Reason $(R)$ is incorrect statement.
  • D
    Assertion $(A)$ is incorrect, but Reason $(R)$ is correct statement.

Answer

Correct option: A.
Both Assertion $(A)$ and Reason $(R)$ are correct statements, and Reason $(R)$ is the correct explanation of the Assertion $(A).$
