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 :

(C) (A) is not correct but ( $\mathbf{R}$ ) is correct.

(A) Both (A) and (R) are correct and (R) is the correct explanation of (A).

(B) (A) is correct but (R) is not correct.

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

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

[Co (en)_{2} Cl_{2}]^{+}

complex ion is three
Reason (R):

[Co (en)_{2} Cl_{2}]^{+}

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.
(C)(A) is not correct but ( $R$ ) is correct.✓ Correct
(D)Both (A) and (R) are correct but (R) is not the correct explanation of (A).

Answer: (C)

Solution

[C o (e n)_{2} C l_{2}]^{+}

shows only TWO geometrical isomers (cis and trans), not three — so Assertion is incorrect. It is octahedral — Reason is correct. So A incorrect, R correct. Option (3).
