9) In a published synthetic procedure, acetone is treated with ethenyl(vinyl) magnesium bromide, and the reaction mixture is then neutralized with strong aqueous acid. The product exhibits the 'H NMR spectrum shown below. What is its structure? When the reaction mixture is (improperly) allowed to remain in contact with ethe aqueous acid for too long, an additional new compound is observed. Its 'H NMR spectrum has peaks at d = 1.70 (s, 3H), 1.79 (s, 3H), 2.25 (broad s, 1H),...
