The complex that can show optical activity is : (A) trans-[Cr(Cl2)(ox)2]3– (B) trans-[Fe(NH3)2(CN)4] — JEE Mains Chemistry Past Papers Chemistry Question
Question
The complex that can show optical activity is : (A) trans-[Cr(Cl2)(ox)2]3– (B) trans-[Fe(NH3)2(CN)4]– (C) cis-[Fe(NH3)2(CN)4]– (D) cis-[CrCl2(ox)2]3– (ox = oxalate)
Answer: D
💡 Solution & Explanation
Only cis-[CrCl2(OX)2]3– show optical isomerism while its trans form do not show optical isomerism due to presence of plane of symmetry.
