Question

Magnesium in Dry Ether

Hint:

Grignard reagents \( (R-MgBr) \) are highly reactive and can be used for nucleophilic addition reactions with carbonyl compounds.

Answer 1

Ethyl bromide reacts with magnesium in dry ether to form an ethyl magnesium bromide (Grignard reagent). \[ \text{C}_2\text{H}_5\text{Br} + \text{Mg} \xrightarrow{\text{dry ether}} \text{C}_2\text{H}_5\text{MgBr} \]
