# How many resonance structures does CH3O- have?

Nov 25, 2015

#### Answer:

The negative charge on the oxygen atom is conceived to be localized on the oxygen centre. And it has no resonance isomers available.

#### Explanation:

The methoxide anion is conceptually a much stronger base than hydroxide; so that, should it placed in water, proton transfer to methanol and hydroxide formation would occur.

${H}_{3} C {O}^{-} + {H}_{2} O \rightarrow {H}_{3} C O H + H {O}^{-}$

Of course, methoxide anion can also act as a nucleophile.
