Lab #5: Grignard Reaction – Synthesis of Triphenylmethanol John Kang Chem 152L Performed: 7/20/04 Date submitted: ________________ Lab Partners: Sang Lee‚ Vicky Lai TA: John Stanko Abstract: This experiment explored the synthesis of triphenylmethanol through the use of Grignard reagents. The percent yield of the product was 10% on a relatively humid day. The melting point was calculate to be 127.2oC with a literature value of 162oC. An IR spectrum of the product was taken and used

Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration

My Reaction to Apollo 13 The movie Apollo13 is great but little kind of boring. Tom Hanks is a great artist! He is my idol. One of his great movie is Forrest Gump. By the way‚ The Apollo13 is America’s third moon landing mission. En route‚ an onboard explosion deprives their spacecraft of most of its oxygen supply and electric power‚ forcing NASA’s flight controllers to abort the Moon landing‚ and turning the mission into a struggle to get the three men home safely. I thought Jim’s wife was his

Observing the and determining the reaction rate of photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is

ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi and the reaction rate

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Biology 104 Reaction Times Objectives: 1. Formulate and test hypotheses regarding reaction times. Introduction: Reaction time is a measure of how quickly an organism can respond to a particular stimulus. Reaction time has been widely studied‚ as its practical implications may be of great consequence‚ e.g. a slower than normal reaction time while driving can have grave results. Many factors have been shown to affect reaction times‚ including age‚ gender‚ physical fitness‚ fatigue‚ distraction
