stability‚ elimination A. Introduction. The dehydration of alcohols is an ELIMINATION reaction that is commonly used to form alkene molecules. The mechanism for the dehydration of alcohols consists of transforming the –OH functional group into a better leaving group by using a strong acid to protonate the alcohol. After –OH has been transformed into –OH2+‚ it becomes easier to break the σ-bond between the O and the C and for elimination to occur to form the alkene π-bond. This elimination mechanism

cyclohexanol was dehydrated to cyclohexene through an elimination reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used. The formation of the product was verified by performing a Bromine test as well as an analysis using IR Spectroscopy. A percent yield of 8.33% was obtained. Introduction: In an elimination reaction‚ two substituents are removed from a molecule

Excretion and Elimination of Toxicants and their Metabolites The first topic that was covered by this chapter was the excretion of wastes by the Renal system. The first step that occurs in the kidney deals with the nephron‚ which is the functional unit of the kidney. In the glomerulus the formation of urine begins with the passive filtration of plasma through the pores that are found in the glomerulus. The plasma is forced through these pores by hydrostatic pressure. The only things that determines
