REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

hydroxide is an inorganic compound with the formula KOH‚ commonly called caustic potash. Along with sodium hydroxide (NaOH)‚ this colorless solid is a prototypical strong base. It has many industrial and niche applications. Most applications exploit its reactivity toward acids and its corrosive nature. In 2005‚ an estimated 700‚000 to 800‚000 tonnes were produced. Approximately 100 times more NaOH than KOH is produced annually. KOH is noteworthy as the precursor to most soft and liquid soaps as well as numerous

Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions‚ and write net ionic equations for precipitation reactions‚ as well as to identify spectator ions‚ perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate‚ copper (II) nitrate‚ iron (III) nitrate‚ barium

EXPERIMENT TWENTY Qualitative Analysis of Anions Analysis of Solutions Containing the Ions Cl-‚ Br-‚ l-‚ SO42-‚ CO32-‚ and NO3- This experiment continues the qualitative analysis begun in Experiment 19. Here we will be analyzing solutions to determine the presence of anions. The same techniques that were used for the cation analysis must be used for the anions. If you have not carried out Experiment 19‚ read the introductory section before starting this experiment. The major difference

reaction. The conversion of 1-butanol to 1-bromobutane relies on sulfuric acid which plays two important roles. First‚ it protonates the alcohol of 1-butanol to form an oxonium ion which is a good leaving group. Secondly‚ it produces the hydrobromic acid‚ the nucleophile‚ which attacks 1-butanol causing the oxonium ion to leave and forming 1-bromobutane. However‚ using sulfuric acid in this experiment has several downsides. First‚ it poses a huge safety hazard as it can cause severe burns. Secondly

ELECTRONEGATIVITY This page explains what electronegativity is‚ and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules. If you are interested in electronegativity in an organic chemistry context‚ you will find a link at the bottom of this page. What is electronegativity Definition Electronegativity is a measure of the tendency of an atom to attract a bonding pair

method (a). In the second step‚ immobilization and solubilization were performed by sonicating the mixture of Fe3O4 and mercaptosuccinic acid in water (b). Thirdly‚ Pd2+ and Ni2+ ions attached on to the surfaces of the Fe3O4 spheres by using the interaction between the S-H groups of the mercaptosuccinic acid and the metal ions and self-assembled (c). In the next step‚ the growing process initiated by the addition of NaBH4 (d)‚ and Pd-Ni/Fe3O4 core-shell structures were made after crystal growing

Mn+ ions in which M is any arbitrary metal. The two half cells are linked together by a wire running from one electrode to the other. A salt bridge also connects to the half cells. Through electrochemistry‚ these reactions are reacting upon metal surfaces‚ or electrodes. An oxidation-reduction equilibrium is established between the metal and the substances in solution. When electrodes are immersed in a solution containing ions of the same metal‚ it is called a half-cell. Electrolytes are ions in
