Preparation of Ethyl 3-Coumarincarboxlate Ivy Akatsa Organic Chemistry Introduction Knoevenagel Condensation uses a compound of the type X-CH2-Y as the carbanion source‚ where X and Y are the electron withdrawing groups such as –CN‚-COOR‚-COR‚ NO2‚ etc. These groups are capable of stabilizing an adjacent carbanion by resonance. So in this experiment‚ the Knoevenagel Condensation of diethyl malonate with aromatic aldehyde salicylaldehyde involves an initial aldol-type addition followed by a spontaneous

INFRARED SPECTROSCOPY: FUNDAMENTALS AND APPLICATIONS Barbara H. Stuart University of Technology‚ Sydney‚ Australia 72 Infrared Spectroscopy: Fundamentals and Applications hydrocarbons appear in the 3000–2800 cm−1 range and the C–H stretching bands of methyl groups and methylene groups are readily differentiated. For methyl groups‚ asymmetric C–H stretching occurs at 2870 cm−1 ‚ while symmetric C–H stretching occurs at 2960 cm−1 . By comparison‚ methylene groups show asymmetric stretching at 2930

meat also. These bacteria in the root nodules have an enzyme called ___nitrogenase____ that helps them split the Nitrogen molecules into other forms. 6. The process the microbes go through to break the mainly toxic ammonia molecule into __nitrite__ (NO2- ) and ___nitrate__ (NO3-) is called ___nitrification__. 7. When these smaller molecules are taken up into plant tissue the term is __Assimilation__. 8. When decomposers (the microorganisms that do most of Earth’s recycling) break down decaying organic

This bacterium can also grow with or without O2. If located in anaerobic habitat it can it will use the fermentation process producing mixed acids and gases (Todar 2012). This bacterium has shown that it can also use anaerobic respiration when NO3 or NO2 is available. Chemicals‚ pH‚ temperature‚ are a few signals that determines how E.coli will respond (Todar 2012). When it senses a change in the environment it can swim toward or away from anything useful or harmful. Temperature can also affect E.coli

This paint‚ dubbed KNOxOUT by Boysen‚ can destroy pollutants specifically harmful NOx Gases (NO‚ NO2 and N2O) in large amounts‚ at rates comparable to full-grown trees. This project‚ if successful‚ would combat the pollution produced by hundreds of vehicles passing through EDSA everyday which for me‚ is already a big headstart. In my opinion‚ this
