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

Book review of The Firework Maker’s Daughter The story is about a firework maker called Lalchand and his daughter‚ Lila‚ who also wanted to be a firework maker. One day Lila runs away to get the last ingredient needed to be a successful firework maker. In a volcano Lila finds the royal sulphur (the last ingredient) but she was in danger of burning. Her friend Chulak‚ and the white elephant Hamlet‚ save her from the flames of the lava by giving her some fireproof water from the goddess of the

Nitrogen Family (The traditional name for the elements in Nitrogen’s column‚ the “pnictogens”‚ comes from a Greek word for “choking” or “strangling”) P.7 Nitrogen: Fritz Haber discovered how to convert the Nitrogen in the air into an industrial product. Although nitrogen gas can suffocate those who are unsuspecting‚ tends to be benign‚ almost to the point of uselessness. The one important thing it can do is replenish the soil; it is as important to plants as vitamin c is to us. When pitcher

(calcium oxide) + carbon dioxide (thermal decomposition) To make lots of quicklime we use a lime kiln 1) fill the kiln with crushed limestone 2) heat it strongly with a supply of hot air quicklime comes out of the bottom of the kiln‚ waste gases leave at the top. Usually the kiln rotates to ensure that the limestone is thoroughly mixed with the stream of hot air and it therefore decomposes completely. 1.3 Decomposing carbonates Calcium is in group two‚ as is magnesium‚ so we can expect magnesium carbonate

Topic 11a – Group 7‚ the Halogens Revision Notes 1) Trends in physical properties of the elements • At room temperature‚ Cl2 is a pale green gas‚ Br2 is a brown liquid‚ I2 is a blue-black solid. • In Group 7‚ boiling point increases down the group because the molecules have more electrons and‚ therefore‚ stronger van der Waal’s forces which require more energy to overcome them • Electronegativity is the ability of an atom to attract the electrons in a covalent bond • Down

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of
