The base catalyzed Knoevengael condensation of butyl cyanoacetate and corresponding aldehyde led to the forming Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. The analyses that were used to prove its composition and structure

The solvent chosen depends highly on its polarity as this will be the characteristic that will separate the different substances. Petroleum‚ ether‚ hexanes‚ cyclohexanes and toluene are some examples of solvents with different polarities as well as increasing polarities.

Transfer contents to a 25mL Erlenmeyer flask and add 3mL of toluene (if the crystals do not dissolve then the contents may be heated). Add about 3mL of petroleum ether until slight cloudiness continues then heat the flask until the solution is clear. Crystals should form as the solution cools to room temperature

Tyler Kerschner HN English 11 1 May 2013 It’s a Fracking Problem Fracking is increasing in the U.S.‚ but with this increase of natural gas comes an increase of safety concerns. The process of hydraulic fracking requires chemicals that can affect the families that live nearby. These chemicals also affect the environment on the land and in the air. With fracking there comes its positives and its negatives‚ some good and some bad. There are very few regulations on how fracking can be done‚ but

CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds
