Grignard Reaction: Synthesis of Triphenylmethanol Dominic DiRaimo Lab Partners: Roxana Hernandez Somata Thach TA: Sreya Mukherjee December 5‚ 2013 Introduction Grignard reagents are good nucleophiles as well as strong bases (Weldegirma). It allows compounds to react with acidic compounds‚ therefor is must be free from acids as well as water during the desired reaction. Another important aspect of Grignard reagent is that refluxing is necessary to

1. In the Luminol synthesis the compound being oxidized was the sodium hydrosulfite. 2. The purpose of the acetic acid is to pronate the dianon organic molecule to make the neutral organic compound‚ Luminol that will crash out of the solvent. If the number of moles were reversed for acetic acid and sodium hydroxide the solution would be very basic‚ and and the amount of Luminol produced would decrease. 3. The cold water was used to decrease the solubility of Luminol in the solvent and prevent further

In the experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including

First‚ the synthesis of the coordination compound‚ KaFeb(ox)cdH2O‚ needed to be carried out. This was achieved by weighing out 8.29 grams of K2C2O4 with a Dial-a-gram balance. Once measured‚ the 8.29 grams K2C2O4 were placed in a 125 mL Erlenmeyer flask. 25 mL of deionized water were then added to the 125 mL flask and stirred with the K2C2O4 until complete dissolution was achieved. Next‚ 4.11 grams of FeCl3 were weighed out using the balance previously mentioned. Once the 4.11 grams were measured

Describe and evaluate one neurobiological and one psychological theory of the function of dreaming The first neurobiological theory I will look at is the activation-synthesis theory. These theory sees dreams as activation in the brain in the areas to do with perception‚ action and emotion (which occurs during REM). They are essentially random as there is an external blockade (at the top of our spine resulting in paralysis so we cannot act out our dreams) and an internal blockade as only areas

Caroline Treinen Ms. Pajer English 101 Synthesis Essay Who are we to dictate who someone loves? The definition of love is the action that two people share. The definition does not say love only occurs between a man and a woman. The article‚ “Gay marriage proposals destructive to society‚ Vatican official says‚” is an argument against gay marriage. The author‚ John Thavis‚ claims that homosexuals are just struggling to find themselves and that same-sex marriage disrupts the normal sexuality

Procedure 2.0 g of Mo(CO)6 and 10 mL of mesitylene were added into a 50-mL round bottom flask along with a small magnetic stir bar. A 30-cm reflux condenser was attached to the round bottom flask and a gas inlet was then connected to the condenser and to the bubbler. Since Mo(CO)6 and the product tends to react with oxygen at high temperatures this reaction must take place in an inert atmosphere. Therefore‚ the gas inlet was connected at the top of the condenser to a nitrogen source and was flushed
