Question
Which of the following will have three stereoisomeric forms?<br>(i) [Cr(NO3)3(NH3)3]<br>(ii) K3[Co(C2O4)3]<br>(iii) K3[CoCl2(C2O4)2]<br>(iv) [CoBrCl(en)2]
Answer: A
💡 Solution & Explanation
Both [CoCl2(C2O4)2]3- and [CoBrCl(en)2]+ have a trans form (meso/inactive) and a cis form that exists as a pair of enantiomers (d and l), giving 3 stereoisomers each.
