A) \[cis-{{[CrC{{l}_{2}}{{(ox)}_{2}}]}^{3-}}\]
B) \[{{[Co{{(en)}_{3}}]}^{3+}}\]
C) \[trans-{{[CrC{{l}_{2}}{{(ox)}_{2}}]}^{3-}}\]
D) \[{{[Co(ox){{(en)}_{2}}]}^{+}}\]
Correct Answer: A
Solution :
trans\[{{[CrC{{l}_{2}}{{(ox)}_{2}}]}^{3-}}\] isomer-optically inactive (superimposable mirror images and plane of symmetry). cis \[-{{[CrC{{l}_{2}}{{(ox)}_{2}}]}^{3-}},{{[Co{{(en)}_{3}}]}^{3+}}\]and \[{{[Co(ox){{(en)}_{2}}]}^{+}}\] exhibited optical isomerism.You need to login to perform this action.
