Dressen-Chemical Bonding Outline

Chemical Bonding: What we did last year and what we will do! : 

Types of Bonds A. Covalent (sharing electrons) i. Polar Covalent (0.0-0.3) ii. Non-Polar Covalent (0.3-1.7) B. Ionic (exchanging electrons) ( > 1.7) C. Metallic (Lecture tomorrow) Octet Rule Electron Dot Notation Chemical Bonding: What we did last year and what we will do!

Slide 2: 

IV. Lewis Structures (Work on today) A. Lone Pairs vs. Shared Pairs B. Procedure for Drawing Lewis Structures of a Compound 1. Number of atoms of each type 2. Write electron dot notation of each atom 3. Determine # of valence electrons 4. Arrange atoms to form skeletal structure for molecule a. Carbon always in center b. Hydrogen never in center c. Least electronegative atom in center d. Connect atoms by electron pairs e. Add lone pairs f. Elec. in your structures = total valence elec. C. Multiple Bonds … Double and Triple Bonds D. Resonance Structures

Slide 3: 

V. Molecular Geometry A. VSEPR Theory B. Geometry Types Linear Bent Trigonal Planar Trigonal Pyramidal Tetrahedral C. Hybridization (Lecture Tomorrow) VI. Intermolecular Forces (Lecture Wed.)
