To which one the group belongs depends on how it stabilizes or destabilizes the transition state. The ortho position refers to the two adjacent positions on a benzene ring. Anisole Ortho Para Aromatic Substitution Mechanim Organic Chemistry Books Chemistry Chemistry Classroom It depends on the substituent on the phenyl ring. Ortho para meta positions benzene ring . 9132020 The three general positions of a disubstituted benzene ring are ortho meta and para. The meta position refers to the positions separated by one carbon atom on a benzene ring. The same thing happens in the case of a benzene ring. Electron withdrawing groups like -CHO removes electron density from benzene ring and position 246 orthopara become electron deficient or we can say position 35 meta become electron rich in comparison to ortho or para so substitution takes place at meta position. The key difference between ortho para and meta substitution is that ortho substitution has two substituents in 1 and 2

Instead of using numbers to indicate substituents on a benzene ring ortho- o- meta- m- or para p- can be used in place of positional markers when there are two substituents on the benzene ring disubstituted benzenes. 02102019 Updated October 02 2019. Orientation Of Products Substituent In Monosubstituted Benzene Derivatives Ortho Meta Para Substitution Resonance Structures Hybrid Methylbenzene Chlorobenzene Phenol Nitrobenzene Benzoic Acid Effect On Synthesis Routes Advanced A Level Organic 16052020 Some examples of directive influence of functional group in mono substituted benzene are explained below. Para position of monosubstituted benzene . For example chlorine Cl attached to a phenyl group would be named chlorobenzene chloro benzene. Due to the resonance in the benzene ring electron density at ortho and para position increases as compared to the meta position. If substitution were totally random an orthometapara product ratio of 221 would be expected. These groups di
