Organic Chem Flashcards
Why carbon?
4 valence e. - can form 4 bonds
- abundant in nature
Organic Chem
Old definition
The study of molecules that make up life
Ex. DNA, carbs, fatty acids, lipids
New definition of organic chemistry
The study of carbon containing compounds
Types of synthetic organic molecules that we can make in the lab
Plastic, nylon, polyester, teflon, TNT
Most common elements in organic chem other than CARBON
N, S, Cl, Br, I, P, F
What types of carbon contain compounds are NOT considered organic
CO, CO2, any carbonate salt (___CO3)
Prefixes to tell # carbons in molecule
1-10
Meth Eth Prop But Pent Hex Hept Oct Non Dec
What does suffix depend on
The class (types) of organic molecules it is
Alkanes
- hydrocarbons (contains only C &H)
- suffix “ane”
- highly flammable
What or larger are there structural isomers

Alkenes
- uses suffix “ene”
- has a double bond between 2 carbons
- when counting main chain:
1) main chain MUST include the carbons with the double bond
2) the double bonded carbons MUST be given the lowest # poss.
For Alkenes which one do you have to indicate which carbon
Butene and above
Cis
Hydrogen/side group on a double bond are on the same side
- usually better than trans
- less efficient packing, easier to break apart
Trans
Hydrogen/side group on opposites
-more efficient, harder to break down
