Question

In a reaction where iron (III) chloride reacts with hydrochloric acid, what is the expected outcome?

• A. The reaction forms a simple complex.
• B. The reaction forms a complex with different coordination.
• C. The reaction forms a simple bond without coordination.
• D. No reaction occurs.

Hint:

In coordination chemistry, transition metals like iron (III) readily form simple complexes with halide ions in the presence of hydrochloric acid.

Answer 1

The Correct Option is A

Step 1: Understanding the Reaction.
The reaction involves the coordination of iron (III) chloride with hydrochloric acid. This type of reaction typically leads to the formation of a complex between the iron ion and the chloride ions from HCl.
Step 2: Analyzing the Options.
- (A) The reaction forms a simple complex as expected from the interaction between FeCl\(_3\) and HCl.
- (B) A more complex coordination is not formed under these conditions.
- (C) No simple bond formation occurs without the involvement of chloride ions in a coordination.
- (D) A reaction does indeed occur, so no reaction is not the correct answer.
Step 3: Conclusion.
The correct answer is (A) The reaction forms a simple complex.
