Organic Chemistry ( DEFINITIONS ) Flashcards
Organic Chemistry
Study of carbon compounds
- Carbon atoms bonded to other carbon atoms
- Carbon bonded to Hydrogen, Nitrogen, Oxygen, Sulfur, Phosphorus,
and the Halogens
Hydrocarbon
Hydrogen + Carbon
- Simplest organic compound
Saturated Hydrocarbon
Contains only single bonds
- Alkanes
Unsaturated Bonds
Contains only double or triple bonds
- Alkenes + Alkynes
Aliphatic Hydrocarbons
Greek word for “fat” because aliphatic compounds were obtained by heating animal fat
- Structure : Chains
- Alkanes, Alkenes, Alkynes
Alkane
C(n) H(2n+2)
- Saturated Hydrocarbon ( only have single bonds )
Alkene
C(n)+ H(2n)
- Unsaturated hydrocarbon ( contains double bonds )
Alkynes
C(n) H(2n-2)
- Unsaturated Hydrocarbon ( contains triple bonds )
Aromatic Hydrocarbons
Organic compounds containing Benzene rings as apart of their structures
Isomer
Compounds that have the same molecular formulas but different molecular structures
Structural Isomer
Same chemical formula ; Atoms bonded in different arrangements
- Have different chemical and physical properties
Stereoisomers
All atoms are bonded in the same order but arranged differently in space
- 2 types : Geometric Isomer , Optical Isomer
Geometric Isomers
Stereoisomers with different arrangements of groups around a double bond
- Two types :
- Cis — bond are arranged the same on both sides
- Trans — atoms in bonds are arranged diagonally from each other
- Different arrangements affect physical and chemical properties
Optical Isomer
Results from different arrangements of four groups around the same carbon atoms (asymmetrical carbon)
- Isomers end up being mirror images of each other
Chirality
When molecules exist in a right-and-left hand form
