Which of the following will give a pair of enantiomorphs? (en = NH2CH2CH2NH2) [CBSE AIPMT 2007]
A.[Co(NH3)4Cl2]NO2 (b) [Cr(NH3)6][Co(CN)6]
C.[Co(en)2Cl2]Cl✓ Correct
D.[Pt(NH3)4][PtCl6]
Explanation
Enantiomorphs also called enantiomers are pair of molecules as non-superimposable mirror images of each other of a compound and are non-identical to each other. They both rotate the plane of polarized light equally but in opposite direction. Therefore [Co(en)2Cl2]Cl will give a pair of enantiomers. Co Cl Cl en en Co Cl Cl en en + + Hence, the correct option is (c).
