4. Which of the following coordination entity form racemic mixture when mixed in equimolar concentration:
1) [Cr(OX)3]3-
2) [Co(en)2Cl2]+
3) [Co(en)Cl4]-
4)All
Dear Student,
The presence of chelating agents imparts chirality to the coordination molecules and therefore they show optical isomerism. So, all of them if mixed in equimolar quantities will give racemic mixture.
Hence, correct answer is (4)
