Co-Ordination Compounds Question 232
Question: For complex ion/compound formation reactions
(I) $ C{o^{3+}}(aq)+EDT{A^{4-}}\xrightarrow{{}}P $ (II) $ N{i^{2+}}( aq )+dmg( excess )\xrightarrow{NH_4OH}Q $ (III) $ Z{n^{2+}}( aq )+gly( excess )\xrightarrow{{}}R $ (IV) $ P{t^{4+}}(aq)+en,(excess)\xrightarrow{{}}S $ which of the following complex ion/compound does not exhibit optical activity?
Options:
A) P
B) Q
C) R
D) S
Show Answer
Answer:
Correct Answer: B
Solution:
$ N{i^{2+}}(aq) $ with DMG (dimethylglyoxime) form square planar complex which is obtically inactive.
While $ {{[Co(EDTA)]}^{-}},{{[Zn{{(gly)}_2}]}^{2+}} $ and $ {{[Pt{{(en)}_3}]}^{4+}} $ are optically active as they do not have P.O.S.
