Abstract: The purpose of this lab is to prepare phenylmagnesium bromide‚ a Grignard reagent‚ and react it with benzophenone to give triphenylmethanol. Once made‚ the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone‚ benzophenone. The result is an alkoxide that is then protonated to give the alcohol‚ triphenylmethanol. The purity of the final product will then be considered by melting point and IR spectroscopy. Final purified triphenylmethanol weighed 8.02 grams

2014 Preparation and IR Analysis of 2-chloride-2-methylbutane Line Reaction Abstract The purpose of this experiment was to react 2-methyl-2-butanol with concentrated HCl in order to form 2-chloride-2-methylbutane. The hydrogen for the HCl make the -OH from the 2-methyl-2-butanol into a good leaving group because H2O is formed. The H2O leaves and Cl- is free to bond with the carbocation creating 2-chloride-2-methylbutane. The materials needed for the lab were an Erlenmeyer flask with a stir

Abstract: The purpose of this lab was to synthesize triphenylmethanol from benzophenone and bromobenzene by the formation of a Grignard compound with the reagents bromobenzene and magnesium metal. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product. The mixture was then mixed with sulfuric acid and the organic layer was extracted via a separatory funnel. The mixture was then recrystallized from methanol and was allowed

History of Toys. Toys are anything that can find and that can be used for play. The children of the world have been playing with toys that have existed in many forms with different materials since the very beginning of its history. Toys have been a part of most children‚ a part of society and culture all over the world for thousands of centuries. Everyone has a favorite toy from their childhood. Once can remember their grandmothers had gave me a doll was made from two balls‚ scrap yarn‚ buttons

A Synthesis of Safrole and o-Safrole W.H. Perkin & V.M. Trikojus J. Chem. Soc. 1663 (1927) HTML by Rhodium No direct synthesis of safrole has been recorded‚ the most recent attempt being that of Baker and Robinson (JCS‚ 1925‚ 127‚ 1424)‚ who distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide‚ but obtained isosafrole‚ the double bond moving into the position of greater stability.

In Simply Good News‚ N.T. Wright presents the argument that the Gospel is in fact news‚ it is good‚ and applicable now. Moreover‚ Wright suggests that we currently occupy the space between what has taken place and the coming event that has yet to happen. These ideas are intricately woven with scriptural evidence in hopes of promoting an accurate view of the Gospel among Christians and non-Christians alike. The text begins with a description of the term ‘news’. “For something to qualify as news

Gravimetric Analysis of a Chloride Salt CHEM 1001 Purpose: To illustrate typical techniques used in gravimetric analysis by determining quantitatively the chloride content in an unknown soluble salt. Theory: AgCl(s) is a very insoluble solid‚ yet still does have some solubility. Because of these traits‚ the following reaction is able to occur: Ag+(aq) + Cl−(aq) → AgCl(s) . This reaction is able to occur in both directions. When a soluble silver salt such as AgNO3 is added to a solution containing

Introduction The purpose of this experiment is to synthesize methyl nitrobenzoate from methyl benzoate‚ concentrated HNO3‚ and concentrated H2SO4 via an electrophilic aromatic substitution reaction. Reaction Procedures/ Observations Use a 50 ml beaker to cool about 6 ml of concentrated sulfuric acid in an ice water bath. Weigh the vial containing about 3 grams of methyl benzoate and add it to the cooled sulfuric acid. Next pour about 2 ml of sulfuric acid to the nitric acid in the vial
