organic chemistry
study of all compounds containing carbon
Hydrocarbons
the simplest organic materials, containing only the elements hydrogen and carbon
aliphatic hydrocarbon
A hydrocarbon with carbon atoms joined together in straight or branched chains. Not
aromatic.
aromatic hydrocarbons
hydrocarbons that contain one or more benzene rings
3 types of aliphatic hydrocarbons
alkanes - these have their carbons arranged in chains or rings and contain only C-C
single bonds
alkenes - these have their carbons arranged in chains or rings and contain at least one
C=C double bond
alkynes - these have their carbons arranged in chains or rings and contain at least one
C≡C triple bond
Alkanes are
the simplest of the hydrocarbons, having the general formula CnH2n+2, where n is the
number of carbon atoms
saturated hydrocarbons
hydrocarbons that contain only single bonds between carbon atoms / the simplest class
of hydrocarbons / each carbon atom is bonded to as many hydrogen atoms as possible
alkane nomenclature
1-meth
, 2-eth
3-prop
4-but
5-pent
6-hex
7-hept
