1. The problem statement, all variables and given/known data Basically I have to show the product of this reaction: 2. Relevant equations Grignard reaction mechanism: The conversion of a ketone to an alcohol 3. The attempt at a solution My attempt of this reaction produces an alcohol with two ethyl groups attached to the central carbon as well as a phenyl group and an OH group attached to the central carbon, so the IUPAC name would be 3-phenyl-3-pentanol. However, the answer is: Can someone please explain why the reaction produced an alkene instead of an alcohol. I do not know why this occurred and need some clarification. Also, when does this extra step occur. Thanks.
