Answer:
The Grignard reagent will be destroyed
Explanation:
The Grignard reaction is based on a carbanion production (RMgX). If water is present in the glassware, a reaction can take place with [tex]H_2O[/tex] and the desired product will not be produced. Because an "H" would be transferred from water to the Grignard reagent. (See figure 1)
If we have acetone in the glassware we will have a similar problem. The Grignard reagent would be destroyed and the desired product will not be produced. The Grignard reagent will attack the carbon in the carbonyl group and the carbanion would disappear. (See figure 2)
