Organic
• Organic refers to compounds containing carbon, and often hydrogen, oxygen, and other non-metal elements
• Three common characteristics:– Bonds are covalent (non-ionic)– Each carbon forms a total of four bonds– Carbon atoms can be bonded to each other or
to other nonmetal atoms (hydrogen, halogens, oxygen, nitrogen, etc)
Hydrocarbons
• Simplest type of organic compound consisting solely of hydrogen and carbon atoms
# Carbons Root Name
1 Meth-
2 Eth-
3 Prop-
4 But-
5 Pent-
6 Hex-
7 Hept-
8 Oct-
Alkanes
• Saturated Hydrocarbons: single bonded carbon atom
• Have the ending “-ANE”
Ethane
Alkenes
• Unsaturated Hydrocarbons: double bonded carbon atom
• Have the ending “-ENE”
Ethene
Alkynes
• Unsaturated Hydrocarbon with a triple bonded carbon atom
• Have the ending “-YNE”
Ethyne
Alkyl Groups
Chains that are added on to hydrocarbons and affect nomenclature, being preceded by numeric indication of their location
Methyl: CH3---
Ethyl: CH3---CH2
Propyl: CH3--- CH2--- CH2
Branched Chains
• When a hydrocarbon is not a straight-chain, the naming is more complex
• The suffix indicates parent chain
• The prefix indicates branching group the number indicates its location
Geometric Isomers
• Same formula but different orientation
• Cis same side of carbons
• Trans different side of carbons
Cis-2-Butene Trans-2-Butene
Joke Time….
• Name this compound:
Answer….
• ¡¡¡TRANSPARENT!!!
Aromatics
• Derived from the single compound of Benzene, C6H6, which is in a hexagonal shape (three single / three double bonds).
• Functional groups bonded to compound are named as a prefix to “-benzene”
Chlorobenzene
Functional Group Orientation
• Isomers of benzene have three prefixes for orientation of dual functional groups
Para- Meta- Ortho-
1,4-dichlorobenzene 1,3-dichlorobenzene 1,2-dichlorobenzene
