are attached or bonded to hydrogen
atoms
hydrocarbons
It is the study of all compounds
other than hydrocarbons and their
derivatives

Characteristics of organic compounds
- covalent bonds
- liquids, solids
- low melting points
- soluble in organic solvents
- aque do not conduct electricity
- all burn
- reactions are slow

in 18th century scientists categorized compounds into two types:
Organic -living organisms
Inorganic- from minerals
who proved the vital force theory is wrong?
Friedrich Wohler (1828)
it is the study iof all substances other than hydrocarbons and their derivatives
Inorganic chemistry
Properties of organic chemistry:
Covalent bonds low melting point insoluble in water aqueous sol dont donduct electricity all burn rxns are slow
Inorganic chemistry properties:
ionic bonds highmelting points soluble in water insoluble in inorganic solvents aqueous sols conduct elec few burn rxns are fast
ways to attain 4 bond requirement:
bonding with other 4 atoms; 4 single bonds
bonding with other 3 stoms; 2 single bonds and 1 dounble bond
bonding with other 2 atoms; 1 single bond and 1 triple bonds
classifications of carbon:
primary carbon
secondary carbon
tertiary carbon
quaternary carbon
is a chemical formula that gives the total number of atoms of each element in each molecule of a substance
Molecular formula
Example: CH4, C2H6
Structural formula types:
Expanded formula
condensed structural formula
.Skeletal
Line-bond
– is a representation that gives the
exact number of each atom in a compound as well as
the bonding arrangement of the atoms and the type of
bond present at each atom.
expanded formula
– is a two-dimensional structural
representation that shows the bonding arrangement of the
atoms.
structural formula
each carbon atom and its attached
hydrogen atoms are written as a group. More detailed
than the molecular formula.
condensed structural formula
– structural arrangement of all
bonded carbon atoms without showing the attached
hydrogen atoms.
Skeletal structural formula
the quickest representation in
which a line represents a carbon–carbon bond. A
carbon atom is understood to be present at every point
where two lines meet (at the intersection) and at the
ends of each line.
Line-bond structural formula
two different compounds, by formatin, but have the same molecular formula
Isomerism
are compounds that have the same molecular formula (thatis, the same numbers and kinds of atoms) but that differ in the way the atoms are arranged; same molecular formula, ARE DIFF COMPOUNDS WITH DIFF PROPERTIES
Isomers
same molecular formula, differ in arrangement of the carbon chain
Skeletal isomerism
same molecular formula, differ in the connectivity
constitutional isomerism
kind of stereo isomer that mirror image of each other
enantiomers
aka ciis-trans isomerism
Diastereomers
compound with bondage of carbon and hydrogen
Hydrocarbons
Hydrocarbons in which all carbon-to-carbon bonds are
single bonds and are the simplest type of organic
compound
Saturated
Hydrocarbons with one or more carbon-to-carbon multiple bonds (double bond, triple bond, or both)
Unsaturated
compounds with benzene rings
Aromatic
Open chains (acyclic) and cycclic
Aliphatic
HC derivatives involving oxygen
Alcohol, phenol, ether, aldehyde, ketone, carboxylic acid, ester
HC derivative involving nitrogen
Amines
HC derivative involving nitrogen and Oxygen
Amides
HC derivative involving halogen
Alkyl halides
HC derivative involving sulfur
Thiols
is an atom or a group of atoms with
characteristic chemical and physical properties. This determines
the shape, properties, and the type of reactions of a molecule.
The study of functional groups and their reactions provide the
organizational structure for organic chemistry.
functional group
it is an acyclic unsaturated hydrocarbon that contains one or mmore carbon-carbon double bonds
Alkene
is cyclic unstaurated hydrocarbon that contains two or more C-C double bonds within the ring system
cycloalkene
is a compound used by insects and some animals to trnasmit a message to other members of the same species.
Pheromone
is an acyclic unsaturated hydrocarbon that contains one or more c-c triple bonds
Alkyne
is an unsaturated cyclic hydrocarbon that does not readily undergo addition reactions
