Which is not true about Grignard reagent?
Correct answer: B. They are very stable compounds and can be isolated easily.
- A. They are highly reactive compounds.
- B. They are very stable compounds and can be isolated easily.
- C. They have synthetic importance.
- D. They are represented by the general formula RMgX.
Explanation
The correct answer is They are very stable compounds and can be isolated easily. This statement is false because Grignard reagents are highly reactive and sensitive to moisture and air, which makes them unstable and difficult to isolate. They are usually prepared and used immediately in situ. Conversely, the other options are true: Grignard reagents are highly reactive, important for synthetic applications, and are represented by the formula RMgX.
