This is the reason why grignard reagent should be prepared in a dry medium (without water or moisture). Grignard reagent + water → alkane + MgX(OH) Alkane is given such as protecting number of carbon atoms contains in the grignard reagent. Why bother with all these precautions? Well, because water is the natural enemy of the Grignard reagent, and of organometallic reagents in general . Not only will water react irreversibly with your Grignard, the molecular mass of water is so low that a little goes a long way, and ineptly dried solvent or glassware will seriously reduce your yield. Consider (finally)!

Add solvent. Click on the water and add it to the flask. Assume that a volume of ~10 mL was added.

Hence, water Grignard reagents are highly reactive and react with any source of proton to give hydrocarbons. Even water, alcohols, amines are sufficiently acidic to convert A grignard reagent is basically an organomagnesium halide having a formula of be kept dry to avoid the resulting Grignard reagent from reacting with water. Why grignard regents are so much reactive with water?
Grignard Reagents R-X R-MgX (Grignard reagent) Mg(0) THF R-X can be an alkyl, vinyl, or aryl halide (chloride, bromide, or iodide) Solvent: diethyl ether (Et 2O) or tetrahydrofuran (THF) Alcoholic solvents and water are incompatible with Grignard reagents and organolithium reagents. Reactivity of the alkyl halide: -I > -Br > -Cl >> -F

If the water is added before the Grignard reagent has reacted with the aldehyde, then the reaction won't occur. We will discuss why this happens later in this lesson. A. The Grignard reagents can react with water to yield alkanes that can disrupt other reactions.
