If youre confused between nitro (NO2) and amine (NH2), then please search it up and dont mislead others. Im always open to further revisions, so if theres a functional group thats missing that you think should be included, let me know in the comments below. This group is a common ring group. The alkane ( -ane ) has a higher priority than the nitro group, so the nitro group will not be used to a suffix. Halogens come down at the rock botoom. Thus, benzene is part of an aromatic functional group. I have a question. While this chart still doesnt claim to be exhaustive, it contains almost double the number of functional groups as the original chart (40 vs. 21). But if both double and triple bond are not on the terminal carbons, prioritization is given to the triple bond. Free Radical Initiation: Why Is "Light" Or "Heat" Required? And if alkyne present at lower locant than alkene so alkyne will written with lower no of carbon atom. under the alkyl halide section, 2nd to last priority just above nitro.
