Determining Aromaticity & Conjugation: Practice Problems

WebWhen the nitrogen atom of an aromatic heterocycle has single bonds only, then the nitrogen is still sp 2 hybridized, but the lone pair occupies the unhybridized p orbital to create aromaticity. This lone pair is part of the conjugated pi electron system and is not available to react as a weak base. Exercise 6. WebThe naming process for 2-chlorophenol (o-chlorophenol). Note that 2-chlorophenol = o-chlorophenol. Below is a list of commonly seen benzene-derived compounds. Some of these mono-substituted compounds (labeled in red and green), such as phenol or toluene, can be used in place of benzene for the chemical’s base name.
