What is the correct general formula of Grignard reagent?
Correct answer: D. RMgX
- A. RMX
- B. R2MgX
- C. RMgX2
- D. RMgX
Explanation
The general formula for Grignard reagents is RMgX, where R is an organic group (such as alkyl, aryl, or vinyl) and X is a halogen (typically bromine, iodine, or chlorine). The most common Grignard reagent is probably methyl magnesium bromide, which has the formula CH3MgBr.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
