Grignard and organolithium reagents are powerful bases. Because of this, they cannot be used as nucleophiles on compounds which contain acidic hydrogens. If they are use, they will act as a base and deprotonate the acidic hydrogen rather than act as a nucleophile and attack the carbonyl. A partial list of functional groups which cannot be used are: alcohols, amides, 1o amines, 2o amines, carboxylic acids, and terminal alkynes. Determine the product of a reaction in which one of the...

Diethyl ether is a good solvent to be used with Grignard reagents. Which of the following explanations for this laat alle! It can serve as a Lewis base and stabilize the Grignard reagent. It has a very high boiling so it can be heated to drive the Grignard formation to completion. It is polar enough to stabilize the Grignard reagent. It is aprotic and thus is not acidic enough to react with the Grignard reagent.
