Huckel Samenvattingen, Aantekeningen en Examens

Samenvatting van het vak structuurchemie gegeven in leerjaar 1 van de opleiding chemie aan Avans Hogeschool

This course presents an introduction to quantum mechanics. It begins with an examination of the historical development of quantum theory, properties of particles and waves, wave mechanics and applications to simple systems — the particle in a box, the harmonic oscillator, the rigid rotor and the hydrogen atom. The lectures continue with a discussion of atomic structure and the Periodic Table. The final lectures cover applications to chemical bonding including valence bond and molecular orbital...

What are the four rules for writing resonance structures? Correct Answer 1. Atoms must not be moved. Only electrons. 2. All resonance atoms must lie in the same plane. 3. Only valid Lewis structures are allowed. 4 . The number of unpaired electrons must remain constant. What are the two conditions for resonance? Correct Answer 1. An atom must have a P orbital or a lone pair of electrons. 2. It must be single bonded to an atom that has a double or triple bond. The latter comprom...

(Physico-Chemical Properties of Drugs) Changes the solubility, metabolism, and excretion properties of the drug within the limits of the biological target. Electrolytes Ionic/ weak acid or base Hydrogen Bonds Hydrogen bonds form between polar groups Interaction between an electronegative atom (O, N, S) and a polarized hydrogen. Polarized H i...

Chapter 18 EAS Questions and Answers 100% correct Electrophilic Aromatic Substitution -reaction in which an electrophile is substituted for a hydrogen on an aromatic ring -many different types of EAS reactions based on what functional group replaces the hydrogen Alkene vs Benzene Alkenes undergo addition reactions but Benzenes react differently under similar reagents. Don't confuse the two, one is Aromatic and the other isn't. Aromatic Requirements The organic structure must...

This document contains digitally taken, handwritten notes for the introduction to aromatic compounds chapter. Notes in this chapter cover aromaticity, including Huckel’s number. It also includes a list of the most common aromatic compounds that must be memorized, naming di- and tri- substituted benzene derivatives. Lastly, it includes reactions on the side chain of a benzene ring, showing mechanisms as necessary as well as notes that further explain anything that may be difficult to understa...
