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.
CH 3 OC 6 H 5 + (CH 3 CO) 2 O → CH 3 OC 6 H 4 C(O)CH 3 + CH 3 CO 2 H. Unlike most acetophenones, but reflecting the influence of the methoxy group, methoxyacetophenone undergoes a second acetylation. Many related reactions have been demonstrated. For example, phosphorus pentasulfide (P 4 S 10) converts anisole to Lawesson's reagent, [(CH 3 OC ...
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. It occurs widely in nature and is a common product of the pyrolysis of wood. [3]
Dimethyl ether (DME; also known as methoxymethane) is the organic compound with the formula CH 3 OCH 3, (sometimes ambiguously simplified to C 2 H 6 O as it is an isomer of ethanol). The simplest ether , it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for ...
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.

[4,3] 4/m 3 2/m, m 3 m order 48: full octahedral symmetry: This group has the same rotation axes as O, but with mirror planes, comprising both the mirror planes of T d and T h. The three-fold axes give rise to four D 3d subgroups. The three perpendicular four-fold axes of O now give D 4h subgroups, while the six two-fold axes give six D 2h ...
