Electrophilic Aromatic Substitution and Substituted Benzenes. Electrophilic aromatic substitution is a general reaction of all aromatic compounds, including polycyclic aromatic hydrocarbons, heterocycles, and substituted benzene derivatives. A substituent affects two aspects of the electrophilic aromatic substitution reaction: 1.

What is the structure of benzene? 3. What is aromaticity? 4. How is aromatic stability calculated? 5. Write a molecular orbital diagram of benzene. Write an orbital diagram of any aromatic polygon. 6. Determine which organic cyclic cations and anions are aromatic, anti-aromatic or not aromatic. 7. Determine the aromaticity of heterocylics. 8.

Polycyclic aromatic hydrocarbons are classified into two main groups, low and high molecular weights, based on their physical and biological properties and number of fused aromatic rings contained in their structure. Light or low molecular weight (LMW) PAHs consist of 2-3 aromatic rings, and heavy or high molecular weight (HMW) PAHs

Polycyclic aromatic hydrocarbons (PAHs) are a class of organic pollutants that contain two or more fused aromatic rings composed of hydrogen and carbon. PAHs can also have alkyl groups, such as methyl and ethyl groups, substituted for one or more of their hydrogen atoms, and are generally considered to include heterocyclic aromatic compounds, where

Polycyclic aromatic hydrocarbons (PAHs) are a class of fused-ring multi-aromatic ring compounds that are ubiquitous environmental pollutants caused by fossil fuel combustion (Brooijmans et al., 2009). They are comprised of two or more fused aromatic rings with a diverse range of branching types. Although aromatic molecules

1. Polycyclic Aromatic Hydrocarbons (PAHs) 1.1a General Properties Polycyclic aromatic compounds including both polycyclic aromatic hydrocarbons (PAHs) and heterocyclic compounds form one of the most heavily studied classes of environmental pollutants [1,2,3,4,]. This widespread interest stems from the demonstrated carcinogenic activity of many .

polycyclic aromatic hydrocarbons (PAHs). Polycyclic aromatic hydrocarbons are undoubtedly the most widespread carcinogens in the environment (Harms et al., 2003) and are commonly associated with the disposal of combusted materials or petroleum residues (Suess, 1976). Polycyclic aromatic hydrocarbons are a group of ubiquitous hydrocarbon .

Aromatic Nucleophilic Substitution Reaction via Benzynes (Arynes) . It resembles the arenium ion mechanism of aromatic electrophilic substitution. In both the cases the attacking species forms a bond with the substrate, giving an intermediate, and then the leaving group departs, i.e., both involve an addition .

The aromatic ring is electron-poor (electrophilic), not electron rich (nucleophilic) The “leaving group” is chlorine, not H The position where the nucleophile attacks is determined by where the leaving group is, not by electronic and steric factors (i.e. no mix of ortho–and para- products as with electrophilic aromatic substitution).

Aromatic hydrocarbons can undergo substitution or displacement reactions by attack of an electro philic, nucleophilic, or free-radical species. The most common aromatic substitution reactions, how ever, involve the attack of an electrophilic reagent on the aromatic ring, e.g., nitration, sulfonation, halogena
