To produce tert-butyl chloride from tert-butyl alcohol 2. To understand the SN1 and SN2 mechanism involved in the reaction 3. To determine the yield of percentage of t-butyl chloride II. Introduction An alkyl halide is a derivative of alkanes. Alkanes are hydrocarbons with a functional group C-C. The hydrogen atom is then replaced by a halogen (F‚ Cl‚ Br‚ I). Therefore‚ alkyl halides are compounds that have a halogen atom bonded to a saturated‚ sp3 hybridized carbon atom. These could be classified

Xxx.comTheories of light In the seventeenth century two rival theories of the nature of light were proposed‚ the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave‚ and that this wave was propagated through a material called the ’aether’. Since light can pass through a vacuum and travels very fast Huygens had to propose some rather strange properties for the aether: for example; it must

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Chemical Formulas Review: Nomenclature and Formula Writing Naming Simple Compounds There are four naming systems you should familiarize yourself with to succeed on the SAT II Chemistry exam. The trick is recognizing which naming system to use. Here are the guidelines: * If the compound starts with H‚ it is an acid. Use the naming acids rules. * If the compound starts with C and contains quite a few H’s and perhaps some O’s‚ it is organic. Use the naming organic compounds rules. *
