Question
Indicate the complex/complex ion with did not show any geometrical isomerism: ladqy@ladqy vk;u tks dksbZ Hkh T;kferh; lek;ork iznf'kZr ugha djrk gS] og gS% (A) [Co(NH3)4Cl2]+ (B) [CoCl2(en)2] (C) [Co(NH3)3(NO2)3] (D) [Co(CN)5(NC)]3+
Answer: D
💡 Solution & Explanation
(1) [Co(NH3)4Cl2]+ show cis-trans isomerism. (2) [CoCl2(en)2] show cis-trans isomerism. (3) [Co(NH3)3(NO2)3] show fac-mer isomerism. (4) [Co(CN)5(NC)]3+ can’t show geometrical isomerism due to the presence of plane of symmetry.
