R-Mg-Br is called___________________?
Correct answer: C. Both A & B
- A. Grignard reagent
- B. Metallic alkyl halide
- C. Both A & B
- D. Alkyl
Explanation
R-Mg-Br is an organomagnesium halide called a Grignard reagent, and it contains an alkyl group directly bonded to a metal, so it is also described as a metallic alkyl halide. A student may select only Grignard reagent by overlooking the descriptive classification, or only metallic alkyl halide by not recognising the special name.
