Question

Assertion :cis - $\left[Fe\right(en{)}_{2}C{l}_2{]}^{+}$ can form racemic mixture. Reason: cis - $\left[Fe\right(en{)}_{2}C{l}_2{]}^{+}$ is optically active square planar complex.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

The cis form of [Fe(en)₂Cl₂]⁺ forms non-superimposable mirror image as shown in the figure. Thus, they are a pair of enantiomers or racemic mixture.

cis-[Fe(en)₂Cl₂]⁺ is an octahedral complex with hybridization of central metal d²sp³.

Hence, Assertion is correct but Reason is incorrect.

Option C is correct.
