What are polycyclic compounds give 2 examples?
Some examples of polycyclic organic compounds include naphthalene, anthracene, pyrene, and the benzopyrenes. A number of polycyclic hydrocarbons pose hazards to human health. For example, benzo(a)pyrene from automobile exhaust and tobacco smoke is known to be a carcinogen .
How many types of PAHs are there?
There are at least 10,000 different PAH compounds. Most are formed from the incomplete combustion of plant or animal matter, or carbon fuels, such as coal or petroleum.
Is Mercury a VOC?
Volatile Organic Compounds: Lead and Mercury.
Is heptane a VOC?
Volatile organic compounds, or VOCs, are substances that contain carbon and evaporate (becomes a vapor) or “off-gases” at room temperature. Some examples of VOCs include benzene, methylene chloride, hexane, toluene, trichloroethane, styrene, heptane, and perchloroethylene.
Is CO2 a VOC?
Some common gases such as carbon dioxide CO2, carbon monoxide CO, and carbonic acid, are not included in the classification as VOCs because they are not particularly reactive or volatile.
Is benzene a VOC?
Common examples of VOCs that may be present in our daily lives are: benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene.
Is acetone a VOC?
A rather potent chemical, acetone is found in common products such as nail polish remover, furniture polish and wallpaper. Yet not only is acetone one of the most common VOCs out there, meaning it’s harmful to human health in high doses.
Is toluene a VOC?
Toluene, benzene and styrene are volatile organic compounds (VOCs) widely distributed in the environment. Tobacco smoke, traffic exposure and solvents used for paints, rubber and adhesives are known sources for these compounds.
Is ozone a VOC?
VOCs are an important pollutant because of their contribution to the formation of ground-level ozone. When VOCs are released into the atmosphere, they react with nitrogen oxides (NOx) to create ozone molecules.
Which compound is said to be an aromatic compound?
Aromatic compounds are chemical compounds that consist of conjugated planar ring systems accompanied by delocalized pi-electron clouds in place of individual alternating double and single bonds. They are also called aromatics or arenes . The best examples are toluene and benzene. Aromatics require satisfying Huckel’s rule.
How to identify an aromatic compound?
It must be cyclic.
What are the uses of aromatic compounds?
It is used as a starting material for the preparation of varieties of aromatic compounds which are used for the manufacture of dyes,drugs,perfumes,explosives,etc.
What are the characteristics of aromatic compounds?
Aromatic compounds are generally nonpolar.
