A graduate student was studying nucleophilic addition reactions of ketones. To start with, she added ethyl iodide to a flask containing anhydrous ether and chunks of magnesium metal. The result was an exothermic reaction and the ether in the flask started boiling. After the ether stopped boiling, she added 2-butanone to the flask and the ether started boiling again, indicating another exothermic reaction. After the reaction mixture cooled down, she added dilute acid to the mixture and separated the aqueous and ether layers. She evaporated the ether layer and purified the obtained product. GC-MS analysis of the purified product shows the presence of a major product with a few impurities.
Write the reactions that took place and draw the structure of the major product.
