Question: Which of the following statements is true regarding the complex [Cu(NH3)4]SO4?

Options:

Correct Answer: All of the above

Solution:

In [Cu(NH3)4]SO4, copper is in +2 oxidation state, NH3 is a monodentate ligand, making the statement \'All of the above\' incorrect.

Which of the following statements is true regarding the complex [Cu(NH3)4]SO4?

Which of the following statements is true regarding the complex [Cu(NH3)4]SO4?

Step 1: Identify the complex ion in the formula [Cu(NH3)4]SO4. The complex ion is [Cu(NH3)4].
Step 2: Determine the oxidation state of copper (Cu) in the complex. Since sulfate (SO4) has a -2 charge and NH3 is neutral, Cu must be +2 to balance the charge.
Step 3: Understand that NH3 is a ligand that can donate one pair of electrons to the metal. This means NH3 is a monodentate ligand.
Step 4: Analyze the statement 'All of the above' regarding the oxidation state of copper and the nature of NH3. Since both statements are true, 'All of the above' cannot be incorrect.
