RankGuru · Accepted Answer

**Grignard Reagents ($R-MgX$)** are organometallic compounds of immense synthetic importance.
- Synthesis: $R-X + Mg \xrightarrow{	ext{dry ether}} R-Mg-X$
- **Dry Ether Solvent**: It is crucial because Grignard reagents are highly reactive toward moisture (proton sources). Ether also stabilizes the reagent by coordinating to the Magnesium atom.
- Nature: The $C-Mg$ bond is highly polar ($C^{\delta-} - Mg^{\delta+}$), making the R group a very **strong nucleophile** and a strong base.
