WebAromatic compounds react mainly by electrophilic aromatic substitution, in which one or more ring hydrogens are replaced by various electrophiles. Typical reactions are ... 4 NO2+ There are 16 valence electrons available (N = 5, and 2 O = 2 6 = 12 for a total of 17, but we must subtract 1 electron since the ion is positive). WebAromatic compounds consist of compounds that are cyclic, possess a conjugated system, satisfy Huckel’s law, and are commonly planar. As the name suggests, cyclic structures form rings, as opposed to branching chain structures. Aside from a ring shape, aromaticity involves a continuous pi system. import bootstrap in html

WebAromatic compounds play key roles in the biochemistry of all living things. The four aromatic amino acids histidine, phenylalanine, tryptophan, and tyrosine each serve as one of the 20 basic building-blocks of proteins. Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The word "aromatic" originates from the past grouping of molecules based on smell, before their general chemical properties are understood. The current definition of aromatic compounds does not have any relation with their smell.
