The carbon–metal bond in organometallic Grignard reagents exhibits significant covalent character. However, we can treat these compounds as electron-rich carbanions because of the large difference in electronegativity between carbon and magnesium. These reagents are great to form carbon–carbon bonds but must be kept in an anhydrous environment to work effectively. Show the curved arrow mechanism in the box on the left and both products for the reaction between water and the effective carbanion resulting from butylmagnesium bromide in the other two boxes. Make sure you place the product derived from butan-1-ide in the middle box and the product formed from water in the box on the right. Do not show the magnesium and bromide in your answer.
