In which case racemic mixture is obtained on mixing its mirror images in `1:1` molar ratio?A. (a) `[Cr(en)_3]^(3+)`B. (b) `[Ni(DMG)_2]`C. (c) `cis-[Cu(Gly)_2]`D. (d) All of these |
|
Answer» Correct Answer - A (a) `[Cr(en)_3]^(3+)` exists in d- and l-forms due to the absence of one of the symmetry element(s). So it will give racemic mixture when d-and l-forms are mixed in `1:1` molar ratio. (b) `[Ni(DMG)_2]` has square planar geometry and thus has mirror plane so optically inactive. (c) cis`-[Cu(Gly)_2]` has square planar geometry and thus have mirror plane so optically inactive. |
