Introduction to Chem Flashcards
is a chemistry of carbon compounds.
Organic Chemistry
the study of compounds that contain carbon. It is one of the major branches of chemistry.
Organic Chemistry
In ancient era, this was used as a pain killer.
Willow Bark
In the early 1800’s Who first defined organic chemistry as a branch of modern science.
Jon Jacob Berzelius
if they originated in living or once-living matter
Organic compound
if they came from “mineral” or non-living matter.
Inorganic compound
discovered that urea - an organic compound - could be made by heating ammonium cyanate (an inorganic compound).
Frederich Wohler
Form stable covalent bonds to other carbon atoms
Catenation
Importance of Carbon
- Can form single,double,yriple bonds
- Long Carbon chain can be produced
- Will bond to many other elements
- A huge number of chemicals is possible
is the linkage of atoms of the same element into longer chains.
Catenation
occurs most readily in carbon, which forms covalent bonds with other carbon atoms to form longer chains and structures
Catenation
is the reason for the presence of the vast number of organic compounds in nature.
Catenation
is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon.
Organic compound
is a major component of all organic compounds, including carbohydrates, lipids, proteins, and nucleic acids.
Carbon
is the term for the conversion of an organic substance into carbon or a carbon-containing residue through pyrolysis or destructive distillation
Carbonization
The chemical compounds of living things are known as___________? because of their association with organisms and because they are carbon-containing compounds.
Organic compounds
Four major categories that are found in living things
- Carbohydrates
- Lipids
- proteins
- Nucleic acids
*Usually Covalent
*Generally Weak
*Gases, liquids or lowmelting-point solids
*Often Flammable
*Insoluble
*Non-conductor
*Slow and complex
Organic Compound
*Often ionic
*Quite Strong
*Usually highmelting-point solids
*Usually nonflammable
*Soluble
*Conductor
*Fast and simple
Inorganic compound
Different types of formula
- Molecular formula
- Empirical formula
•Structural formula
•Condensed formula
•Bond-line formula
Actual number of atoms of each element in a molecule
Molecular formula
Simplest ratio number of atoms of each element in a molecule
Empirical formula
shows all atoms in the bonds, Bonds are represented as lines
Structural Formula
Shorthand way of writing Molecular formula
Condensed Formula
