What is the mechanism for base-catalyzed transesterification with methanol where the ester reacts with an alcohol solvent to form a new ester that contains the alcohol's OR group? Please draw out mechanism and explain. the reaction will use the reagents XS NaOCH3 (from NaOH, CH3OH) to convert vegatable oil (a fatty acid triester) to glycerol and 3 moles of methyl oleate (biodiesel)

Restoring self-control when intoxicated. Does coffee or some other form of stimulation really allow a person suffering from alcohol intoxication to “sober up”? Psychologists from the University of Waterloo investigated the matter in Experimental and Clinical Psychopharmacology (February 2005). A sample of 44 healthy male college students participated in the experiment. Each student was asked to memorize a list of 40 words. The students were then randomly assigned to one of four treatment groups (11 students in each group). Students...

EXPERIMENT 20 CSI: SMU Part 2. Synthesis of an Ester. Esters are compounds of the form RCOOR'. They occur naturally in many plants and animals, and can be synthesized. They have a pleasant aroma usually described as "fruity of flowery". In a Fisher esterification an ester is formed from the reaction of a carboxylic acid and an alcohol with a strong acid as a catalyst. The OH contained in the carboxylic acid group 1s replaced with the alkoxy group (O-R")...

If an ester labeled in the carbonyl oxygen with 18O is reacted with aqueous NaOH, what would be the result? Hint 1. How to reason this out In light of the addition-elimination mechanism, consider the fate of the tetrahedral intermediates formed in the reaction. ANSWER: Recovered ester would have less of the label than at the beginning of the reaction. The alcohol from the hydrolysis would contain the 18O label. Recovered ester would now have the 18O in the alkoxy...

4. Using your knowledge of Le Chatelier's principle and the given equation, explain why an excess of acetic acid is used in this experiment. 5. If water was added as the solvent in this reaction would this shift the equilibrium in the desired direction to form more of the product (the ester)?

What is the influence of alcohol in the body? Please be specific and give at least 2 influences, ie influence in the GI tract, etc. Please be sure to enumerate these (so there is no confusion), ie. (1) and (2). Please also give 2 examples of alcohol's damage. Talk about at least 1 short-term effect and 1 long-term effect. Lastly, give your views on alcohol consumption and why you feel the way you do. You must complete at least 10...
