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 –C n H 2n+2 Alkenes –One or more double bonds between C’s –The root is –ene –C n H 2n Alkynes –One or more triple bonds between C’s –The root is –yne –C n H 2n-2

Practice C 4 H 10 How many Carbons Draw it Any double or triple bonds? Butane

Practice C 2 H 4 How many Carbons Draw it Any double or triple bonds? Eth ene

Practice C 6 H 14 How many Carbons Draw it Any double or triple bonds? Hexane

Practice C 3 H 4 How many Carbons Draw it Any double or triple bonds? Propyne

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

Practice CH 3 CH 2 CH 2 OH How many Carbons Draw it Any functional groups? Propane x ol

Practice CH 3 CH 2 COOH How many Carbons Draw it Any functional groups? Propane x oic acid
