1.2.3.4.5.6.7.8.Show the curved arrow mechanism for the reaction between ethoxide and methanol to give ethanol and the methoxide ion. 1st attempt Jual See Periodic Table See Hint OH-Ö: Add the missing curved arrow notation.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...
