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
