This is the general chemical structure of the methoxy functional group.
The methoxy functional group is the simplest alkoxy functional group. Todd Helmenstine

An alkoxy group is a functional group containing an alkyl group (carbon and hydrogen chain) bonded to an oxygen atom. Alkoxy groups have the general formula: R-O. An alkoxy group is also known as an alkyloxy group.

  • An alkoxy group bonded to a hydrogen atom is an alcohol.
  • An alkoxy group bonded to another alkyl group is an ether.

Examples: The simplest alkoxy group is the methoxy group: CH3O-.
