1. Daily Starter – Day 55
Using your understanding of electronegativity, determine if C-C is
Non-Polar Covalent
Polar Covalent
Ionic
How about C-H?

2. Carbon Chemistry C4.2 nomenclature C4.8 Carbon Chemistry
A) Structural formulas for up to ten carbon chains
B) Draw Isomers for simple hydrocarbons
Carbon Chemistry

3. Carbon Chemistry Chemistry of Life is organized around carbon.
Carbon accounts for more than 50% dry weight of cells.
Covalently linked C atoms can form linear chains, branched chains, or cyclical structures

4. Alkanes Hydrocarbons with only single covalent bonds (No double bonds)
(saturated – fully soaked in H)
Straight Chains or Branches
Non-polar
Equal sharing of electrons between C-C and C-H bonds

5. Alkenes Hydrocarbons with 1 or more DOUBLE BONDS
UNsaturated –Some H(s) replaced by double bonds

6. Alkynes Hydrocarbons with 1 or more TRIPLE BOND
UNsaturated –Some H replaced by double bonds

7. BUTANE
BUTENE
BUTYNE

8. Functional Groups
These are groups of other atoms added to C-skeletons

9. Aldehydes & Ketones R R C=O within the chain ALDEHYDE KETONE
C=O at end of chain indicated by H
ALDEHYDE
KETONE R R

10. Carbohydrates (Not to be confused with Hydrocarbons)
Class of biomolecules that have aldehydes or ketones
C,H,O

11. Ketone or Aldehyde?

12. Ketone or Aldehyde?
GLUCOSE
FRUCTOSE

13. In-Class Work on Drawing Hydrocarbon Chains
Check in with me after the first 3 drawings
What ever is not finished in class will be HOMEWORK
