  1. Arene substitution patterns

    Arene substitution patterns are part of organic chemistry IUPAC nomenclature and pinpoint the position of substituent s other than hydrogen in relation to each other on an aromatic hydrocarbon . Ortho , meta , and para substitution Image Ortho meta para.svg thumb 150px left Main arene substitution patterns. In ortho substitution , two substituents occupy positions next to each other, which may be numbered 1 and 2. In the diagram, these positions are marked R and ortho. In meta substitution the substituents occupy positions 1 and 3 corresponding to R and meta in the diagram . In para substitution , the substituents occupy the opposite ends positions 1 and 4, corresponding to R and para in the diagram . The toluidine s serve as an example for these three types of substitution. clear Ipso , meso , and peri substitution gallery Image Ipso arene substitution.svg ipso substitution. Image Meso arene substitution.svg meso substitution. Image Peri arene substitution.svg peri substitution. gallery Ipso substitution describes two substituents sharing the same ring position in an intermediate compound in an electrophilic aromatic substitution . Meso substitution refers to the substituents occupying a benzyl ic position. It is observed in compounds such as calixarene s and acridine s. Peri substitution occurs in naphthalene s for substituents at the 1 and 8 positions. Cine and tele substitution In cine substitution , the entering group takes up a position adjacent to that occupied by the leaving group . For example, cine substitution is observed in aryne chemistry. ref GoldBookRef title cine substitution file C01081 ref Tele substitution occurs when the new position is more than one atom away on the ring. ref GoldBookRef title tele substitution file T06256 ref Origins The prefixes ortho , meta , and para are all derived from Greek, meaning straight or correct , following or after , and akin ... gallery References Reflist DEFAULTSORT Arene Substitution Patterns Category Aromatic compounds Category ...   more details

  1. Patterns of Prejudice

    Patterns of Prejudice is a Academic journal journal published by Routledge . Its aims and scope, in part as given by Taylor & Francis , are as follows quote Patterns of Prejudice provides a forum for exploring the historical roots and contemporary varieties of social exclusion and the demonization or stigmatisation of the Other. It probes the language and construction of race , nation, colour, and ethnicity, as well as the linkages between these categories. It encourages discussion of issues at the top of the public policy agenda, such as asylum, immigration, hate crimes and citizenship. As none of these issues are confined to any one region, Patterns of Prejudice maintains a global optic, at the same time as scrutinizing intensely the history and development of intolerance and chauvinism in the United States and Europe, both East and West. br Patterns of Prejudice is a peer reviewed journal published five times a year.
