WebDec 21, 2015 · In both hydroxide and methoxide, we have an $\ce{O}$ bearing negative charge. In the former, we have a hydrogen attached to the $\ce{O}$. In the latter, we have a carbon attached to the $\ce{O}$. Carbon is more electronegative than hydrogen, therefore, carbon should be able to better withdraw electron density via induction from the $\ce{O}$. WebDear learner. Welcome to this issue.

"WebLegalizeChemistry •. Well, with the progression of leaving groups/bases from hydroxide, methoxide, ethoxide, etc, they increase in basicity, indicating they are less stable species and worse leaving groups. The reason is I believe, that alkyl groups are weakly electron donating, more so than just one hydrogen is. " - Ethanethiol vs methoxide

The methoxide ion has the formula of CH3O 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. WebSodium methoxide in methanol is therefore a valuable reagent for rapid transesterification of fatty acids linked by ester bonds to alcohols (e.g. cholesterol, glycerol). It will not esterify free fatty acids or transesterify amide-bound fatty acids in sphingolipids. Also, unlike acidic catalysts, it will not liberate aldehydes from plasmalogens.
