Question

Number of possible isomers for the complex ${[Co(en)_2Cl_2] Cl}$ will be : (en = ethylenediamine)

• A. 3
• B. 4
• C. 2
• D. 1

Answer 1

Answer: (A)

3

Answer 2

${[Co(en)_2 Cl_2]Cl}$ Possible isomers - (i) Geometrical isomers (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
