Week3aStudentOutline.docxStart working on the list of prefixes and suffixes in the addendum found at the back of the outline
- learn all of the IUPAC prefixes
- learn the suffixes –ane through –yl for now
DIVISIONS OF ORGANIC COMPOUNDS
The simplest of the organic compounds are the
-
-
- these two elements can combine in a variety of ways to form other classes of organic compounds
A. Cyclic or Aromatic Compounds
- compounds that are bonded together in a ring formation
1
1)
-
- considered a hydrocarbon
C
/ \
C C OR
I I
C — C
2)
-
- NOT considered a hydrocarbon
- forms a different type of cyclic compound
O
/ \
C C
I I
C — C
B. Acyclic or Aliphatic Compounds
-
- the aliphatic hydrocarbons can then be divided according to the type of bonding present between the carbon atoms
1) Alkanes –
2) Alkenes –
3) Alkynes –
1) Alkanes
- aliphatic hydrocarbons in which all of the carbon to carbon bonds are single covalent bonds
- prefix alk-
- suffix -ane
- with the presence of all single bonds
-
-
- because they are saturated
-
- because you would have to replace a hydrogen if something else was brought in
- there are two other names for the alkanes as a group
a)
b)
- General Molecular formula or Type Formula for the alkanes:
n = number of carbon atoms
2) Alkenes
-
- prefix alk-
- suffix -ene
- with the presence of a double bond
-
-
- if the double bond was broken
- because of being unsaturated
-
- because you could add something to the compound if the double bond is broken
- Alkenes also have two other names as a group:
a)
b)
- General Molecular formula or Type Formula for the alkenes:
n = number of carbon atoms
3) Alkynes
-
- prefix alk-
- suffix -yne
- with the presence of a triple bond
-
-
- if the triple bond was broken
- because of being unsaturated
- the characteristic type of reaction for the alkynes is by addition
- because you could add something to the compound if the triple bond is broken
- Alkynes also have two other names as a group:
a)
b)
