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.
The +M effect, also known as the positive mesomeric effect, occurs when the substituent is an electron donating group. The group must have one of two things: a lone pair of electrons, or a negative charge. In the +M effect, the pi electrons are transferred from the group towards the conjugate system, increasing the density of the system.
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]
An electron donating group (EDG) or electron releasing group (ERG, Z in structural formulas) is an atom or functional group that donates some of its electron density into a conjugated π system via resonance (mesomerism) or inductive effects (or induction)—called +M or +I effects, respectively—thus making the π system more nucleophilic.
Guaiacol (/ ˈ ɡ w aɪ ə k ɒ l /) is an organic compound with the formula C 6 H 4 (OH)(OCH 3).It is a phenolic compound containing a methoxy functional group. Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish.
In Organic chemistry, the inductive effect in a molecule is a local change in the electron density due to electron-withdrawing or electron-donating groups elsewhere in the molecule, resulting in a permanent dipole in a bond. [1]
Ortho esters are readily hydrolyzed in mild aqueous acid to form esters: . RC(OR ′) 3 + H 2 O → RCO 2 R ′ + 2 R ′ OH. For example, trimethyl orthoformate CH(OCH 3) 3 may be hydrolyzed (under acidic conditions) to methyl formate and methanol; [5] and may be further hydrolyzed (under alkaline conditions) to salts of formic acid and methanol.
Trimethyl phosphite is an organophosphorus compound with the formula P(OCH 3) 3, often abbreviated P(OMe) 3.It is a colorless liquid with a highly pungent odor. It is the simplest phosphite ester and finds used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
