Question
Given below are two statements:
Statement-I : $\left\lbrack Fe(ox)_{3} \right\rbrack^{3 -}$ is chiral.
Statement-II : trans - $\left\lbrack Cr\left( H_{2}O \right)_{2}(ox)_{2} \right\rbrack^{-}$is chiral.
(Given : ${oxH}_{2} = HOOC - COOH$ )
In light of the above statements, choose the most appropriate answer from the options given below:
Options
A.Statement-I is correct but Statement-II is incorrect
B.Statement-I is incorrect but Statement-II is correct
C.Both Statement-I and Statement-II are correct
D.Both Statement-I and Statement-II are incorrect
Solution
Sol. [Key Concept: Chirality (optical isomerism) of octahedral complexes]
$\lbrack Fe(ox)\rbrack^{3 -}$ is optically active and chiral with two non-superimposable mirror images.
Plane of symmetry (POS) is present in given species.
∴ It is NOT chiral and optically inactive.
