Naming Organic Compounds

• Organic compounds are composed of mostly Carbon and Hydrogen

• Therefore they are referred to as

hydrocarbons

Hydrogen Carbon

Three part name

• Hydrocarbons have three parts to their name. prefix-root-suffix

• We are going to look at the prefix first

Prefixes

• Meth-1• Eth- 2• Prop-3• But- 4• Pent- 5

• Hex- 6• Hept-7• Oct- 8• Non- 9• Dec- 10

The prefix is simply the number of carbons in the longest chain.

Root• Alkanes

– Have only single bonds between carbons– The root is –ane– CnH2n+2

• Alkenes– One or more double bonds between C’s– The root is –ene– CnH2n

• Alkynes– One or more triple bonds between C’s– The root is –yne– CnH2n-2

Functional group suffixes

• Only two suffixes you need to know

• Alcohols– Have an -OH group attached to the carbon

backbone– Drop e and add -ol

• Carboxylic Acids– Have a -COOH in the formula– Drop e and add -oic acid
