Monday, December 04, 2006 Chemistry ISSUES IN ORGANIC CHEMISTRY How are organic compounds classified? What are their structures? Text: Sections 13.1, 13.4 INTRODUCTION 1. Organic molecules a. C as principle building block 2. Compounds classified by bonding and attachment Ex. Hydrocarbons Contain only H,C a. alkanes: All C - C b. alkenes: have C = C c. alkynes: have C = C ALKANES 1. all C – C a. all sp 3 C’s b. all 109 degrees bond angles c. all tetrahedral shapes 2. Lewis structure for C3H8 H H H H C C C H H H H 24 12 16 8 SP = 1/2 [ER – VE] = ½ ( 40-20) =10 40 20 Condensed structure (C-H bonds not shown) CH 3 – CH 2 – CH 3 OR (no bonds shown) CH 3 CH 2 CH 3
