1. Chapter 11 Organic Chemistry

2. Organic Chemistry
The study of compounds that contain the element carbon
Organic molecules contain carbon
Hydrocarbons (CH4, C3H8, C6H6), various acids (C2H4O2), sugars, proteins, DNA, etc.
Pharmaceuticals, clothes, gasoline, plastic, nearly everything inside of a living organism, etc.

3. Drawing organic molecules
Condensed structures – chemical formula shorthand for organic molecules
Start from left and go to the right, writing the number of H atoms attached to each carbon
CH Condensed structure
C3H CH3CH2CH3
CH3CH2CH3

4. Condensed structures cont.
Repeating regions can be abbreviated in parenthesis

5. Practice Draw out the structures from the condensed formulas CH3CCl3
CH3CH2OBr
CH3(CH2)3NH2
CCl3NH(CH2)2OC(CH3)3

6. Skeletal Structures
Unlabeled junctions/vertices represent carbon atoms
Assume there are enough hydrogens around each carbon to give it four bonds
Heteroatoms (non carbon atoms, N,O, halogens) are drawn with any hydrogens attached as well.
Consider VSEPR geometry as guideline for structures

7. Multiple bonds and rings

8. Practice
Draw the Lewis structure from the following skeletal structures

9. Functional groups
An atom or group of atoms with characteristic chemical and physical properties
Defined by atom connectivity
Structure determines function/properties

10. Organic chemistry
Taking organic molecules and transforming them into other organic molecules
Changing functional groups
Combining molecules

12. Chapter 11 Review Organic molecules Drawing organic molecules
