Question

Given below are two statements :
Statement I : [Co(NH₃)₆] ³⁺ is a homoleptic complex whereas [Co(NH₃)4Cl₂] ⁺ is a heteroleptic complex. 
Statement II : Complex [Co(NH₃)₆] ³⁺ has only one kind of ligands but [Co(NH₃)₄Cl₂] ⁺ has more than one kind of ligands. 
In the light of the above statements, choose the correct answer from the options given below

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Answer 1

The Correct Option is A

Step 1: Understanding the Terms "Homoleptic" and "Heteroleptic"

Homoleptic: A homoleptic complex contains only one kind of ligand.

Heteroleptic: A heteroleptic complex contains more than one kind of ligand.

Step 2: Analyze Statement I

• \([Co(NH_3)_6]^{3+}\) is a homoleptic complex because it has six ammonia (NH₃) ligands.
• \([Co(NH_3)_4Cl_2]^+\) is a heteroleptic complex because it has both ammonia and chloride ions as ligands.

Step 3: Analyze Statement II

• \([Co(NH_3)_6]^{3+}\) has only one type of ligand, ammonia (\( NH_3 \)).
• \([Co(NH_3)_4Cl_2]^+\) has two types of ligands: ammonia and chloride.

Step 4: Conclusion

Both statements are correct, so the correct answer is:

Option (1): Both statements are correct.
