Halides:
- Group 7 elements (Flurine, Chlorine, Bromine, Idodine) can bind to a hydrocarbon chain
- Naming follows standard rules with halides using floro-, chloro-, bromo- and iodo-

EXAMPLES:


1. Name the following compound.


Answer: 2 3 Dibromo Pentane

2. Draw the following compound: 1 Chloro 3 Iodo Propane
Answer:

April 26, 2011 - Alcohols (Angelo)

Alcohols:
- an alcohol is a hydrocarbon with a -OH bonded to it
- some naming rules apply but the parent chain ending with -ol
- The following compound is ethanol...


Multiple -OH:
- if a compound has more than one -OH group, number both and add -dio, -trio, et cetera.

EXAMPLES:


1. Name the following compound.


Answer: 1 Propanol

2. Name the following compound.
 

Answer: 1, 3 Propanediol

Alkenes & Alkynes (double & triple bonds)- brian

- carbon can form double & triple bonds with carbon atoms

- when multiple bonds form fewer hydrogen's are attached to the carbon atom

- naming rules are almost the same as with alkanes
-the position of the double/triple bonds always has the lowest number and is put in front of the parent chain

- double bonds(Alkenes) end in ENE

- triple bonds(Alkynes) end in YNE

Example:

Trans & Cis butene
- if two adjacent carbons are bonded by a double bond and have side chains on them two possible compounds are possible
 

          














Multiple double bonds
- more than one double bond can exist in a molecule

- use the same multipliers inside the parent chain

Example:
