Label each compound as either aromatic (Ar), anti-aromatic (AAr) or non-aromatic (Nar). "Briefly explain" your choice utilizing all aspects of aromaticity. Note, for the next three problems it is required that you provide lone pairs of electrons, orbital and charges onto the appropriate positions of each molecule. Importantly, you must provide the resultant structures involving the aforementioned requirements. "Note, provide the answer where required".

2. Increasing the aromaticity of by fusing more benzene rings together forms a special class of compounds that are called Polycyclic Aromatic Hydrocarbons (PAHs). Primary sources of these compounds are from burning coal, gasoline, wood and trash. These compounds are very persistent organic pollutants and are carcinogenic. We will predict their UV-Vis properties using the Particle-in-a-2- D box model. For the following two aromatic compounds, calculate the wavelength corresponding to the lowest energy wavelength. Should it be a colored compound?...

e 2. One of the criteria for aromaticity is that That is, you can draw resonance structures the following aromatic compounds draw ALL resonance structures to su completely conjugated around the ring. The fi aromaticity is that the pi clectrons in a flatring are completely conjugac mance structures that delocalize pi clectrons completely around the ring conjugated around the ring.
