Katie Smith April 11‚ 2013 Competitive Nucleophiles Introduction The purpose of this experiment was to compare the nucleophilicities of chloride and bromide ions toward the n-butyl and t-pentyl alcohols. We were able to analyze this by using refractometry to measure the amounts of alkyl chloride and alkyl bromide in each reaction. Experiment Scheme (Procedure A) To begin the experiment‚ we assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)

but no single cause has yet to be empirically established. PVFM occurs as the result of a threat to the upper respiratory tract (Mathers-Schmidt‚ 2001). It’s possible etiologies include psychological‚ upper airway sensitivities from laryngeal irritants‚ neurological origins‚ or as the manifestation of an underlying laryngeal dystonia. Psychological factors play a role in the etiology of PVFM‚ because patients with emotional problems such as stress‚ anxiety‚ or depression may exacerbate the problems
