Some of the most useful compounds for organic synthesis are Grignard reagents (general formula R - MgX, where X is a halogen), which are made by combining an alkyl halide, R - X, with Mg. They are used to change the carbon skeleton of a starting carbonyl compound in a reaction similar to that with R - Li:(b) What is the product, after a final step with water, of the reaction between 2-butanone and the Grignard reagent of 2-bromopropane?
