Answer :
The use of anhydrous diethyl ether in Grignard reagent reactions prevents oxygen from forming hydroperoxides, assists in coordination with the reagent, and stabilizes the reagent for better reactivity. The correct answer is: All of the above.
The correct answer is: All of the above. Anhydrous diethyl ether is used in reactions with Grignard reagents for several important reasons:
- Vapors from highly volatile diethyl ether solvent prevent O₂ from reaching the reaction mixture, avoiding the formation of hydroperoxides.
- Ether molecules coordinate with the Grignard reagent through lone pair electrons which form a complex with the magnesium, stabilizing the reagent.
- Ether helps stabilize the Grignard reagent and increases its ability to react due to low reactivity and ability to dissolve nonpolar molecules effectively.
Answer: all of the above
Explanation: Grignards react with O2, and diethyl ether is very volatile, so its vapors prevent O2 from reaching the surface of the mixture and reacting. Ether molecules do coordinate with the Grignard reagent and ether is known to stabilize Grignard reagents
