In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula R−O−CH 3 . On a benzene ring , the Hammett equation classifies a methoxy substituent at the para position as an electron-donating group , but as an electron-withdrawing group if at the meta position.
Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene.The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites.
Alkoxy groups Aryloxy groups. In chemistry, the alkoxy group is an alkyl group which is singularly bonded to oxygen; thus R−O.Denoted usually with apostrophe('). The range of alkoxy groups is vast, the simplest being methoxy (CH 3 O−). [1]
The hydroxymethyl group is a substituent with the structural formula −CH 2 −OH.It consists of a methylene bridge (−CH 2 − unit) bonded to a hydroxyl group (−OH).This makes the hydroxymethyl group an alcohol.
Methoxyacetic acid is a colorless, viscous, and corrosive liquid with a pungent odor which, at 7 °C, freezes to a mass similar to glacial acetic acid. Due to the low solvation energy of its methoxy group, methoxyacetic acid, with a pKa value of 3.57, is more acidic than acetic acid (pKa 4.757) and glycolic acid (pKa 3.832). [3]
2-Methoxyethanol, or methyl cellosolve, is an organic compound with formula C 3 H 8 O 2 that is used mainly as a solvent.It is a clear, colorless liquid with an ether-like odor.
They consist of a disubstituted benzene ring with methoxy group and one methyl group. All three are colorless flammable liquids which are soluble in organic solvents but poorly soluble in water. They are not of major commercial interest although they are precursors to the corresponding methoxybenzoic acids and methoxybenzaldehydes. [1]
