Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product. Table of Reagents: Name Chemical formula Melting Point Boiling Point Density Safety Hazards Diethyl ether C4H10O -116.3°C 34.6°C 0.7134 g/ml Flammable Bromobenzene C6H5Br -30.6°C 156°C 1.5 g/ml

preservation isn’t so good like Head of Senusret III. Both statues have many similarities and differences within each other. For example‚ Yuny and Renenutet is double portrait‚ but Senusret III is a head portrait. Both statues have frontal pose. Yuny and Renenutet medium is limestone and paint‚ meanwhile Senusret III medium is yellow quartzite. Both Yuny and Senusret III are wearing a headdress emphasizing their power and royalty through it. Yuny and Senusret III are statues that have many similarities and

The Solubility of Potassium Nitrate Aim: The aim of this experiment is to find out by how much the solubility of potassium nitrate into distilled water increases when the solution is heated‚ and if yes‚ by how much. Hypothesis: According to data on the internet‚ 3.75 × 10¹ moles of potassium nitrate dissolve in 100g of water. I believe this information may be correct. I also believe that as the solute is absorbing outside heat‚ the energy is increased causing it to dissolve both faster‚ with

It takes a modest amount of research and little more than conversational knowledge of modern history to accurately make the claim that the Jewish people have had an incredibly idiosyncratic relationship with Europe and its many powers throughout ancient and contemporary history. The way they have interacted with various political powers throughout the 20th century is‚ without straying into subjectivity‚ remarkable‚ to say the least. Every nation that has at one point been a home for the Jewish people

Shakespeare portrayed John of Gaunt and King Richard III the way he did because of the political issues and constraints presented to him during his time period. When writing Queen Margaret of Anjou’s role in Richard III‚ however‚ Shakespeare degraded her political influence and public figure because of the social norms and superstitions that confined women under during the Elizabethan era. Yet‚ according to modern-day historian Jacob Abbott‚ there was more to Margaret than Shakespeare told his readers

The Synthesis of Aspirin Chemistry Standard Level Lab Report Data Collection and Processing and Conclusion and Evaluation Date: December 8th‚ 2011 Purpose: The purpose of this lab was to synthesize aspirin‚ determine the theoretical yield‚ compare the percent yield to the theoretical yield and test the purity of aspirin by adding Iron (III) chloride to the product. Hypothesis: I hypothesize that salicylic acid will react with acetic anhydride to produce acetylsalicylic acid (aspirin)

Lab – Solubility Curve for Potassium Nitrate I. Purpose: To plot a solubility curve for potassium nitrate in aqueous solution. II. Safety: Wear eye protection throughout the experiment. Be cautious of hot water. Wash hands if you come into contact with potassium nitrate. III. Procedure: 1. Carefully weigh out your assigned mass of potassium nitrate on a piece of weigh paper. Carefully pour the sample into the large test tube. 2. Add 20. mL of distilled water to the tube.

Abstract – This multi-step synthesis uses aniline as the starting reagent to synthesize five compounds employing several reactions such as acetylation‚ diazo coupling‚ nitration‚ bromination‚ and hydrolysis. The isolated products were analyzed with TLC and spectral data that determined most products were pure while some had a few impurities indicated by GC‚ LC‚ and a wide melting point range was shown for products 2 and 3. The presence of water in product 2 and 7 was indicated by the IR. Acetanilide
