WebThe methoxide ion has the formula of CH 3 O − and is the conjugate base of methanol. It is a strong organic base, and since it is stronger than the inorganic hydroxide ion, it can remove a hydrogen atom from a water molecule, yielding methanol and hydroxide. Therefore, methoxide solutions must be kept free of water.

WebScience Chemistry Explain how each of the following changes affect the rate of the reaction of 1-bromobutane with ethoxide ion in DMF. a. The concentration of both the alkyl halide and the nucleophile are tripled. b. The solvent is changed to ethanol. c. The alkyl halide is changed to 1-chlorobutane. d. The alkyl halide is changed to 2-bromobutane Alkali metal alkoxides are often oligomeric or polymeric compounds, especially when the R group is small (Me, Et). The alkoxide anion is a good bridging ligand, thus many alkoxides feature M2O or M3O linkages. In solution, the alkali metal derivatives exhibit strong ion-pairing, as expected for the alkali metal derivative of a strongly basic anion.
