MCQ
Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$. Assertion $(A)$: The total number of geometrical isomers shown by $\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{+}$complex ion is three

Reason $(R)$: $\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{+}$complex ion has an octahedral geometry.

In the light of the above statements, choose the most appropriate answer from the options given below :

  • A
    Both $(A)$ and $(R)$ are correct and $(R)$ is the correct explanation of $(A)$.
  • B
    $(A)$ is correct but $(R)$ is not correct.
  • $(A)$ is not correct but $(R)$ is correct.
  • D
    Both $(A)$ and $(R)$ are correct but $(R)$ is not the correct explanation of $(A)$.

Answer

Correct option: C.
$(A)$ is not correct but $(R)$ is correct.
c
$\left[\mathrm{Co}(\mathrm{en})_2 \mathrm{Cl}_2\right]^{+}$has octahedral geometry with two geometrical isomers.
