Question

Which one of the following complexes shows optical isomerism? (en=ethylendiamine) (A) trans [C o (e n)2 C l2] Cl (B) [C o (N H3)4 C l2] Cl  (C) [C o (N H3)3 C l3] (D) cis [C o (e n)2 C l2]Cl

Tardigrade Admin · Accepted Answer

[.Co(. (NH)3 .)3(Cl)3]. shows two geometrical isomers and both can't show optical isomerism due to presence of plane of symmetry. Solution

cis [C o (e n)2 C l2]Cl shows optical isomerism Solution

trans [Co (e n)2 C l2]Cl forms identical mirror image due to presence of plane of symmetry. Solution

[.Co(. (NH)3 .)4(Cl)2]. shows geometrical isomerism. Solution
