Question

Which of the following will give a pair of enantiomers? (en $= NH_2CH_2CH_2NH_2$)

• A. $[Cr(NH_3)_6][Co(CN)_6]$
• B. $[Co(en)_2 Cl_2]Cl$
• C. $\left[ Pt \left( NH _{3}\right)_{4}\right]\left[ PtCl _{6}\right]$
• D. $[Co (NH_3)_4Cl_2]NO_2$

Answer 1

Answer: (B)

$[Co(en)_2 Cl_2]Cl$

Answer 2

Enantiomorphs or Enantiomers A pair of molecules related to each other as an object and its mirror images are known as enantiomorphs or enantiomers. These are not superimposable on its mirror image. The example is $[Co(en)_2 Cl_2 ]^+$
Dichlorobis (ethylene diamine) cobalt (III)
