Grignard reagent + h2o
WebThe Grignard reagent will remove a proton from water and be hydrolyzed. For this reason anhydrous (dry) reaction conditions are required. Generally, ethers such as diethyl ether or tetrahydrofuran (THF) are used as the solvent, because they can be dried and they help solubilize the Grignard reagent by coordinating to the positively charged ... Web6 benzoic acid. Grignard reagents are extremely reactive thus the presence of water or oxygen will lead to the formation of an alkane instead of the desired tertiary alcohol. Therefore, it is important for the glassware to be dried thoroughly before proceeding with the procedures and create a closed system. Despite the dried glassware and attempt to …
