Which one of the following complexes shows optical isomerism
Options
- AC o N H 3 4 C l 2 C l
- BC o N H 3 3 C l 3
- Cc i s [ C o e n ) 2 C l 2 C l
- Dt r a n s [ C o e n ) 2 C l 2 C l (en = ethylenediamine)
Correct answer
C. c i s [ C o e n ) 2 C l 2 C l
Step-by-step solution
Complex C o N H 3 4 C l 2 C l have two G.I. which are optically inactive due to presence of plane of symmetry. Complex C o N H 3 3 C l 3 also have two optically inactive geometrical isomers due to presence of plane of symmetry. Complex c i s [ C o e n ) 2 C l 2 C l is optically active due to formation of non-superimposable mirror image t r a n s [ C o e n ) 2 C l 2 C l Complex t r a n s [ C o e n ) 2 C l 2 C l is optically inactive.
