Download Unit 15 Organics Day 2 Cyclic Hydrocarbons: If you remove 2

Unit 15 Organics Day 2
Cyclic Hydrocarbons:
If you remove 2 hydrogen's from the ends of a long chain hydrocarbon you can
form a cyclic hydrocarbon
Unsaturated cyclic hydrocarbons: the arenes
And as a branch on a chain: Phenyl

Nomenclature of alcohols:
1. Name the parent compound using the longest continuous carbon chain containing the hydroxyl
group.
parent name = take off the "e" add "ol" (you can use diol, triol etc if more than one)
2. Number the parent chain to give the lowest possible number to the carbon with the hydroxyl group.
Place this number in front of the name of the parent compound to indicate where the hydroxyl group
is attached.
Nomenclature of ethers:
1. Name the alkyl groups joined by the ether alphabetically followed by the word ether. If the groups
are the same use the "di" prefix.
Nomenclature of Ketones
1. Name the parent compound using the longest continuous carbon chain containing the carbonyl
group.
parent name = take off the "e" add "one"
2. Number the parent chain giving the carbon involved in the carbonyl group the lowest possible
number. This number is placed in front of the name of the parent compound to indicate the position
of the carbonyl in the parent chain.
Nomenclature of Aldehydes
1. Name the parent compound using the longest continuous carbon chain containing the carbonyl
group. parent name = take off the "e" add "al"
2. No numbering needed. The carbon with the carbonyl group is always understood as 1
Nomenclature of Carboxylic Acids
1. Name the parent compound using the longest continuous carbon chain containing the carbonyl
group.
parent name = take off the "e" add "oic acid"
2. No numbering needed. The carbon with the carbonyl group is always understood as 1
