    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.

  3. Ortho effect - Wikipedia

    en.wikipedia.org/wiki/Ortho_effect

    Nitration of m-Nitrotoluene. The ortho effect also occurs when a meta-directing group is positioned in a meta arrangement relative to an ortho–para-directing group, a new substituent introduced into the molecule tends to preferentially occupy the ortho position relative to the meta-directing group rather than the para position.

  7. Proton nuclear magnetic resonance - Wikipedia

    en.wikipedia.org/wiki/Proton_nuclear_magnetic...

    Occasionally, small peaks can be seen shouldering the main 1 H NMR peaks. These peaks are not the result of proton-proton coupling, but result from the coupling of 1 H atoms to an adjoining carbon-13 (13 C) atom. These small peaks are known as carbon satellites as they are small and appear around the main 1 H peak i.e. satellite (around) to

    en.wikipedia.org/wiki/Electrophilic_aromatic...

    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.
