Correct Answer: 1
Solution and Explanation
The correct answer is 1
CoCl3⋅4NH3 ⇒ [Co(NH3)4Cl2]Cl
CoCl3⋅5NH3 ⇒ [Co(NH3)5Cl]Cl2
CoCl3⋅6NH3 ⇒ [Co(NH3)6]Cl3
Only [Co(NH3)4Cl2] can show geometrical isomerism. Hence can exist in cis-trans form.
CoCl3⋅4NH3 ⇒ [Co(NH3)4Cl2]Cl
CoCl3⋅5NH3 ⇒ [Co(NH3)5Cl]Cl2
CoCl3⋅6NH3 ⇒ [Co(NH3)6]Cl3
Only [Co(NH3)4Cl2] can show geometrical isomerism. Hence can exist in cis-trans form.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
