114 MA The following scheme shows two methods to synthesize cyclohexyl methyl ether. Carefully study them and explain in detail, with reaction mechanisms, which of the two methods is better in preparing the desired product. + O Na METHOD A: OCH CH3! METHOD B: OCH + CHEO Na

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
