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
Functional Group
A specific combination of atoms with their own characteristic properties
Halocarbons
Any organic compound containing a halogen (Fluorine, Chlorine, Bromine, and Iodine) substituent
Alkyl Halide
When halogens replace hydrogen in a compound
Aryl Halide
When a halogen atom bonds with a benzene ring/aromatic group
Polymer
Material made of long, repeating chains of molecules
Monomer
Molecule that forms the basic unit of polymers
Natural Polymer
Occurs in nature ; can be extracted from plants or animals and are found in our bodies
Synthetic Polymer
Derived from petroleum oil ( fossil fuels ) and made through chemical reactions
Polyvinyl-chloride (PVC)
3rd most widely used synthetic plastic polymer
Polyvinyl-alcohol (PVA)
Polymer made out of the monomer Vinyl Alcohol
Polymerization
A reaction where monomer units bond rapidly together in a series of steps to form polymer
Additional Polymerization
Monomers bond together through rearrangement without losing atoms/molecules
Condensation Polymer
Monomers containing at least two functional groups combine and lose a small bi-product (usually water)
- Each time a bone is formed, small molecules like water, ammonia (NH2), and HCL are “condensed” out
Thermoplastic Polymer
Polymers that can be melted and molded repeatedly into shapes that are retained when cool
Thermosetting Polymer
Polymers that can be molded when its first prepare, but can’t be remelted after cooling off.
