A Grignard reagent and a ketone are reacted in ether solution and, followed by an acid workup, form a tertiary alcohol. Recall that Grignard reactions must be scrupulously dry in order to work effectively. A common method of drying glassware is to rinse with acetone prior to use.
1. Why is rinsing with acetone not suitable for the reaction stated in the question.
a) Magnesium does not dissolve in acetone.
b) Water dissolves in acetone. Adding acetone will add water to the reaction flask.
c) Magnesium dissolves in acetone. Adding acetone will remove a vital reactant from the flask.
d) Acetone is a ketone. Grignard reagents will react with acetone to make an unwanted byproduct.
