Complex [Co (en) _ 2 C l _ 2 ]Cl has ........ number of possible...

Complex \left[Co{\left(en\right)}_{2}C{l}_{2}\right]Cl has ........ number of possible isomers. (en = ethylenediamine)Complex [Co (en) _ 2 C l _ 2 ]Cl has ........ number of possible isomers. (en = ethylenediamine)Complex [Co (en) _ 2 C l _ 2 ]Cl has ........ number of possible isomers. (en = ethylenediamine)

Options

  1. A2
  2. B1
  3. C3
  4. D4

Correct answer

C. 3

Step-by-step solution

[Co(en)2Cl2]Cl\left[Co{\left(en\right)}_{2}C{l}_{2}\right]Cl

Possible isomers

(i) Geometrical isomers

Complex [Co (en) _ 2 C l _ 2 ]Cl has ........ number of possible isomers. (en = ethylenediamine)

Complex [Co (en) _ 2 C l _ 2 ]Cl has ........ number of possible isomers. (en = ethylenediamine)

(ii) In trans form plane of symmetry present, so trans form is optically inactive but cis is optically active.

Total number of stereoisomer = 2 + 1 = 3
