Give the reaction scheme, showing the products formed (before hydrolysis), when one equivalent of ethylmagnesium bromide is treated with one equivalent of 5-hydroxy-2-pentanone. Does the addition of two equivalents of the Grignard reagent to this, yield a different product? If so, give structure(s).© BrainMass Inc. brainmass.com February 24, 2021, 2:17 pm ad1c9bdddf
Grignard reagents react very readily with any acidic hydrogen - even the hydrogen on an alcohol (-OH) will react (this is why Grignard reactions require very dry solvents). Thus, an alcohol will not be alkylated by a Grignard reagent ...
This solution provides the required information needed for a student to be able to solve this question independently. Since this question involves the use of Grignard reagents, the solution provides an explanation of what these reagents are.
