Functional Groups


Ketone:
- they are carbon compounds
- they have a double bonded oxygen
- has the ending of -one
- the double bond can't be in the beginning or end
- the double bond has to be the lowest number possible

Aldehydes:
- double bonded oxygen
- at either the begging or ending of the parent chain



Alcohols:
- OH (hydroxyl)
- number of Carbons (meth,eth, etc...)
- has the ending of -nol
- phenol is an exception
- has an OH bonded to it
- numbering says where OH is
- more than one OH, add -diol, triol etc...

Ex: methanol










Halides:
- they contain halogens from group 17 (Bromine, Chlorine, Iodine, Fluorine
- the halogens have the ending of -o
- the numbers show where the halogens are

1 Chloroethane


1,2 dichloroethane

Ethers:
- have an ending of -er
- only contains oxygen
- always between 2 carbons
- not in alphabetical order, it's in numerical order
- starts with methyl


Amines:
- has the ending of -yl amine
- nitrogen is placed between each carbon




Amides:
- ends in -anamide
- has a double bonded oxygen and NH2



Nitros:
- starts with nitro-
- has a nitrogen with a double bonded oxygen
- has a single bond oxygen



Esters:
- there is an Oxygen in the parent chain
- double bonded O in side chain
- parent chain ends in -oate
- side chain and "O" sandwich a carbon


Carboxylic Acids:
- use the standard rules but change the parent chain ending to -oic acid
-has a double bonded O and an OH bonded to the first carbon
