The functional group of biphenyl is aromatic ring, benzene. Fax: +30 1 7232 094. If benzene ring is attached with NH2 group then it is called amino benzene.

NH2 group is called amino group. Is it possible to do a Friedel-Crafts reaction on a benzene and get a substituent on the benzene ring from that, and then afterwards add an NH2 group ortho? Also, NH2 groups make benzene rings point towards the ortho/para positions. The molecule benzene, C 6 H 6, first discovered by English physicist and chemist Michael Faraday in 1825, is the smallest molecule that can contain this functional group, and arenes contain one or more benzene (or structurally similar) rings. It is an amino functional group. ! Facile Heterolytic H2 Activation by Amines and B(C6F5)3. Fax: +44 181 981 8745, Department of Chemistry, University of Athens, 15771 Athens, Greece. The functional group is the NH2. I know you cant add NH2 first and then do Friedel-Crafts because anilines cannot undergo Friedel-Crafts. Can You Describe the Smell of Ammonia to Me?
