The structure of a typical methoxy group. 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.
Sodium methoxide is prepared by treating methanol with sodium: 2 Na + 2 CH 3 OH → 2 CH 3 ONa + H 2. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.
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.
Methoxymethanol forms spontaneously when a water solution of formaldehyde and methanol are mixed. [3] [1] or when formaldehyde is bubbled through methanol.[4]In space methoxymethanol can form when methanol radicals (CH 2 OH or CH 3 O) react.
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.
In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions.The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
