This positive charge is however stabilised by the methoxy group, which is a +M group, and destabilised by the nitro group. So from this viewpoint, the methoxy derivative should have been more acidic. membership centralab.coopWebwhether a particular position will be relatively shielded or deshielded by the substituent.

How ortho, para, meta groups of an aromatic molecule are identified in …

WebThese positions are thus the most reactive towards an electron-poor electrophile. This increased reactivity might be offset by steric hindrance between activating group and electrophile but on the other hand there are two ortho positions for reaction but only one para position. Hence the final outcome of the electrophilic aromatic substitution ... WebThis is known as the ortho-para directing effect . The effect can be explained by drawing resonance contributors for the carbocation intermediate of the S E Ar reaction: the positive charge is in position to be delocalized by resonance only in reactions leading to ortho or para substitution.

WebMay 25, 2024 · Which simply leads to the fact that the position farthest from the nitrogen substituted carbon will have the highest electron density (as inductive effect decreases as we move away from the atom causing it). So in this case the best site for attack for the electrophile was para>meta>ortho. WebThere are three relative positions for a disubstituted benzene ring: ortho, meta, and para. All the functional groups are divided into ortho -, para or meta -directors . To which one the group belongs, depends on how it stabilizes or destabilizes the transition state of the electrophilic substitution reaction.

WebFeb 21, 2013 · When to use italics for "para" etc. Jump to solution. I know that italics are required when ortho, meta, and para are included as part of a chemical name (e.g. para -methoxyphenol).
