. Which one of the following complexes shows optical isomerism
A. cis [Co(en)2 C12] C1
B. trans [Co(en)2 C12] C1
C. [Co(NH3)4 C12]
D. [Co(NH3)3 C13] ( en = ethylenediamine)
- The optically active compound is capable of rotating plane polarized light to the right or left.
- cis [Co(en)2 C12] C1 shows optical isomerism. It exists in the form for d and 1 forms.
- Trans isomer is optically inactive meso compound.
The correct option is A: cis [Co(en)2 C12] C1.
