In a particular isomer of [Co(NH3)4Cl2]+, the Cl-Co-Cl angle is 90 , this isomer is known as

  1. optical isomer
  2. cis-isomer
  3. position isomer
  4. linkage isomer.

Answer

(2) cis-isomer

Solution

[Co(NH3)4Cl2]+ is an octahedral MA4B2 type complex showing geometrical isomerism.

Two Cl ligands adjacent to each other ⇒ Cl–Co–Cl angle = 90 ⇒ cis-isomer.

Two Cl ligands opposite to each other ⇒ Cl–Co–Cl angle = 180 ⇒ trans-isomer.
