Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

derivative of the amino acid -carboxamide (VFCA-I toVII ) synthesized through coupling of N-Phthaloyl amino acid chloride derivative (2a-2g- synthesis reported in chapter-1) with 1-(2-amino-1-(4-methoxyphenyl) ethyl)cyclohexanol (VF-II). All the chemicals used are of laboratory grade and purchased from local commercial suppliers and used without further purification. Melting points determined…

Chemical Reaction A Chemical Reaction is when there is change from physical reaction to nuclear reaction. In chemical reaction, there is also a change of a chemical substance to another, which in that case is the change to one or more productions. It 's when a substance changes and when you combine chemicals or mix them, you 'll most likely create a new one, not always but most of the time it will. Cooking food always involves a chemical reaction. It could be from baking a cake by mixing the…

Pyrazolooxazine, QSAR, MPO, HyperChem, Structure-Activity Relationship. 1. Introduction. Oxazinones are important heterocyclics, characterized by a synthetic interest because of their broad biological activities. Considerable attention has been given to these compounds since…

and Hydrochloric Acid Lab, we concluded that the chemical reaction that occurred was exothermic and a single displacement reaction. The experiment consisted of zinc (Zn) and hydrochloric acid (HCl) being mixed in a test tube immersed in water. First of all, bubbles were produced during the reaction. Also, a white powdery substance was produced with properties different from those of any reactant. The bubbles suggest that the reaction was a chemical reaction as bubbles indicate a formation of…

The heterocyclic compounds naming tetrahydrocarbazoles having the significant biological properties. The newly substituted tetrahydrocarbazole derivatives were prepared from substituted phenylhydrazine and cyclohexanone in glacial acetic acid under reflux. These intermediates on reaction with substituted aromatic acid chlorides in alkaline media finally converted to N-Substituted tetrahydrocarbazoles. Fifteen compounds are synthesized and charaterized by their melting point (MP), IR, NMR, MS…

1. Matter can be found everywhere and anywhere. It is anything that takes up space and consists of mass. 2. An element is a substance that includes atoms. These atoms all have the same amount of protons. 3. A compound is formed when two or more separate elements combine and mix together. An example is pure table salt. Table salt is created by two elements which are sodium and chlorine. Sodium and chlorine combine and mix together until the end result which is the table salt. 4. Atoms are…

copper chloride hydrate compound is CuCl2 · 2H2O. Discussion of Theory The technique of gravimetric analysis can be used to find the empirical formula of a compound when the amount of it is known. By dehydrating the copper chloride hydrate sample and using it for an elemental copper-producing chemical reaction, one can isolate the masses of the water, copper, and chloride and determine their mole ratios. Since the Law of Definite Proportions states that a chemical compound always contains fixed…

In this project the aim is to determine the equilibrium constant (Kc) of a weak base when it reacts with a weak acid. The chemicals I wish to determine the equilibrium constant for are, Ethanoic acid (CH3COOH) and Propanol (C3H7OH). To accomplish this, the first question we must ask is, “what is an equilibrium constant and how is it determined”? There are 2 different types of equilibrium. The first, and the type we shall be using is known as homogeneous equilibrium which has everything present…

(2003) Paragraph 1 Crystal chemical relationship between quartz (SiO2) and FePO4 Silicon dioxide is an oxide of silicon with the chemical formula of SiO2. SiO2 is a chemical compound most commonly found in Quartz and it has a space group of P3121. The lattice symmetry of SiO2 is tetrahedron, where there are 4 oxygen atoms covalently bonded to the silicon atom, as shown in Figure 1. Figure 1 - Structure of Silicon dioxide Iron (III) phosphate is a compound with the chemical formula of FePO4.…
