Electron Geometry Lab

Words: 575

Pages: 3

Introduction The purpose of this lab is to practice identifying different molecules, and be able to determine their electron and molecular geometries. And use that to find their different angle. Electron geometry is found by seeing how many electron shells are present, and molecular geometry if found by how many lone pairs are present. The next thing that must be done is to find the polarity of the molecule by combining different solutions together.

Procedure The first model molecules were built to get a better understanding of what each molecule looks like with different amounts of lone pairs. Started by building a tetrahedral, a trigonal by pyramidal, and a octahedral. Then looked at how the shapes of the molecules changed when

Introduction: The purpose of this lab was to study how atoms bonds, how electronegativity affects bonding, and the structures bonded atoms make. In this lab models of an atoms structure were made based on the formulas given. This lab illustrated the effects of electronegativity on bonding, the geometry of atoms, and how VSEPER was important for determining an atoms configuration. There are two types of bonding, ionic and covalent. In the lab, covalent bonding was the only type dealt with, Ionic…

Introduction: Alkenes are hydrocarbons with a C=C double bond. The double bond is stronger than a single bond, yet paradoxically, the C=C double bond is much more reactive than a C-C single bond. Historically, hydrocarbons…

Synthesis and Chemistry of K2S2O8 Essay

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…
