analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted of the benzene ring and methyl group. Acetylsalicylic acid low polarity results from only containing a carboxylic acid and ester and the presence of alkenes in the benzene ring. Ibuprofen was the least polar out of all analgesic drugs because it only contains one carboxylic acid and non-polar functional groups. The behavior of these compounds

EFFECTS OF VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile

bring the resources out. Another con is what they put in the solution. The hazardous solution can contain Benzene (a carcinogen) which has lead to cancer. It also contains Hydrogen sulfide. Hydrogen sulfide can affect the brain and upper-respiratory system. Obviously there is a lot of hidden information about what the oil companies are putting in the solution because if they add things like Benzene or Hydrogen sulfide why wouldn’t they add other chemicals that are hazardous if they don’t have

because of the benzene ring attached to it. The benzene ring is electron withdrawing making it a stronger acid (and weaker base) than the electron- donating ethyl groups that are weaker acid (stronger base). Comparing aniline which is an aromatic amine and benzyl amine‚ which is an aliphatic amine‚ benzyl amine or aliphatic amines in general are stronger bases than aromatic amines. Also‚ it is because in aniline‚ the lone pair present in it is involved in resonance with the aromatic benzene making them

enact laws that protect our environment and petition congress for money to fund alternative fuel research ("Renewable Fuels"). Currently the EPA is fighting to regulate the benzene levels in gasoline by calling for legislation that pushes the levels of benzene lower than they have even been before ("Renewable Fuels"). Benzene has been found to be one of the leading reasons why the burn off of gasoline is so toxic to our environment. However‚ the money is never enough and once enacted‚ even less

Substituents‚ which are attached to the nitrogen atom instead of the carbon of the chain‚ are designated by a capital N. Aromatic amines belong to specific families‚ which act as parent molecules. For example‚ an amino group (—NH2) attached to benzene produces the parent compound aniline. Basicity of amines Amines are basic because they possess a pair of unshared electrons‚ which they can share with other atoms. These unshared electrons create an electron density around the nitrogen
