Functional Groups con'd


Carboxylic Acids
contain a double bonded oxygen with a carbon, and a single bonded base











To name this molecule, you drop the -e of a prefix and add -oic acid
eg ) ethanoic acid


Esters
Similar to carboxylic acids, but in stead you replace the base with an oxygen















Name from where this molecule is closer to the end of a chain. Then add -thyl and ends with -oate.
eg) methyl pentanoate



Ethers
contain an oxygen joining two hydrocarbon groups. Same as naming standard naming rules, change the ending to -oxy.
eg)  1-methoxyethane

CH3-CH2-O-CH3

Look at how the oxygen is attached to the CH3 closer to the right. So it is methoxy. The left over side group is ethane. The name of the whole chain is called 1-ethoxyethane.





Lastly, we covered amines in class. Here's a brief introduction of how to name amines.
