Nmr spectroscopy Study guides, Class notes & Summaries

Allows us to determine the molecule mass and the molecular formula of a compound, as well as some of it's structural featuresMass Spectrometry Tells us the kinds of functional groups a compound hasInfrared (IR) Spectroscopy Provides information about the carbon-hydrogen framework of an organic compoundNuclear magnetic resonance (NMR) spectroscopy A very small sample is placed in a mass spectrometer, where it is vaporized and then ionized (electron removed from each molecule). Electron ...

CHMY 223: ORGANIC CHEMISTRY II (Spring) Prerequisites: Passing grade in CHMY 123, 143 or the equivalent; CHMY 221 C- or better. Organic chemistry is cumulative! Material from CHMY 221 will show up in the quizzes and exams in this course. Course description and objectives: This course is a continuation of CHMY 221 and is an intensive survey of the analysis, structure, reactions and synthesis of the main classes of organic compounds. The course will begin by introducing analytical technique...

What is an alkene and its general formula? It is an unsaturated hydrocarbon with a least one C=C bond. General formula is CnH2n What is a sigma bond? σ single covalent bond formed when two s orbitals overlap. High electron density What is a pi bond? sideways overlap of p orbitals that occur in a double or triple bond. Much weaker than sigma, low bond enthalpy and lower electrostatic attraction Is an alkane or an alkene more reactive? Alkene. contains both sigma and pi bonds with high ele...

Canadian Tax Principles, , Vol 2 (Byrd/Chen) (Answers at the end of each chapter) Chapter 11 (A+ Solutions) 1) ITA 110.2 provides for a deduction of "lump-sum payments", for example a court ordered termination benefit. What tax policy objective is served by this provision? Answer: Such lump-sum payments often reflect compensation for services rendered over several years. The fact that it is received in a single year can result i...
