What are important for the chemistry students
Chapter 1 Skills
Knowledge - Level 1
Terminology to recall from your general chemistry class:
(Note that your textbook has a glossary with definitions)
atomic orbitals: s, p, d
molecular orbitals: sigma and pi bonds
hybrid orbitals: sp, sp2, sp3
types of bonds: ionic, covalent, polar covalent
valence: normal bonding patterns for C, H, N, O, halogens
electronegativity: higher to the right and up the Periodic Table functional groups: alcohols, ethers, carbonyls (aldehydes, ketones),
carboxylic acids
Concepts - Level 2
The Periodic Table: periodic trends in valence, electronegativity, etc. Lewis structures: all electrons shown Kekule structures: lines represent bonds line structures: omit Cs and Hs condensed structures: abbreviations for standard structural units
VSEPR: method of identifying preferred 3D structures
hybridization: hybrid orbitals allow optimum bonding
functional groups: carbon and oxygen bonding patterns, isomerism
Applications - Level 3
create appropriate Lewis structures, including formal charges recognize different resonance forms for a given molecule interpret Kekule, line, and condensed structures
identify polar bonds and direction of polarity
Analytical Skills - Level 4 & higher
identify the hybridization of a given atom or a given bond using hybridization or VSEPR, write good 3D structures for molecules
