Alkoxide vs. Phenoxide — What's the Difference?

An alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They are written as RO−, where R is the organic substituent.

See phenolate.

An organic compound in which the hydrogen of the hydroxyl group of an alcohol has been replaced by a metal.
