Functional Groups: Organic Chemistry
functional group
groups on a molecule that have high chemical reactivity

alkanes
hydrocarbon molecule with no functional group

alkenes
hydrocarbon that has double bonds acting as functional group

alkynes
hydrocarbon that has triple bonds that act as functional groups

arenes
six-membered hydrocarbon rings with 3 double-bonds (typically have strong aromas or smells)

haloalkanes
molecule that contains a carbon-halogen bond that acts as their functional group

alcohols
molecule that contain a hyrdroxy group (-OH) as its functional group

ethers
molecule whose functional group is 1 oxygen bonded to 2 carbons

carbonyl groups
molecule whose functional group is a carbon double-bonded to an oxygen (3 types include: aldehyde, ketone, carboxylic acid)

aldehyde
type of carbonyl group where the oxygen is double bonded to a carbon and that carbon is bonded to a hydrogen

ketone
type of carbonyl group where the oxygen is just double-bonded to the carbon

carboxylic acid
type of carbonyl group where the oxygen is double bonded to a carbon which is bonded to a hydroxide

amide
alkyl group containing nitrogen instead of carbon (typically only making 3 total bonds)

thiols
sulfur replaces the oxygen in the hydroxy group of an alcohol

alkyl
an alkane (hydrocarbon with no functional groups) with one hydrogen removed (typically represented by R)

isopropyl

isobutyl

tert-butyl

neopentyl
