The number of stereoisomers possible for \(\left[ Co ( ox )_{2}( Br )\left( NH _{3}\right)\right]^{2-}\) is ...... . \([ ox =\) oxalate \(]\)
- A \(5\)
- B \(8\)
- C \(14\)
- D \(3\)
Answer & Solution
Correct Answer
(D) \(3\)
Step-by-step Solution
Detailed explanation
Total number of stereoisomers in \(\left[ Co ( ox )_{2} Br \left( NH _{3}\right)\right]^{2 -}\) i.e. \(\simeq\left[ M ( AA )_{2} ab \right]^{2-}\) \(\rightarrow\) cis is optically active isomers and trans is optically inactive isomer \(\rightarrow\) Hence total isomers is \(=3\)
