Organic Chemistry

Functional Groups


Groups

Groups

Group name: alkyl

Found in:alkanes

2-methyl 3-ethyl pentane


Groups1

Groups

Group name: alkene

Found in:alkenes

but-1-ene

( could also be written: CH2CHCH2CH3 )

If a molecule has at least one alkene group, it is unsaturated


Groups2

Groups

Group name: hydroxyl

Found in:alcohols

butane-1,2-diol


Groups3

Groups

Group name: carbonyl

Found in:aldehydes(if at end of chain), ketones(if not)

propanal

pentan-3-one

( could also be written: HCOCH2CH3 )

( could also be written: CH3CH2COCH2CH3 )


Groups4

Groups

Group name: carboxyl

Found in:carboxylic acids

propanoic acid

( could also be written: HOOCCH2CH3 )


Groups5

Groups

A carboxylic acid can lose its proton (H+) to become a

carboxylate anion

propanoate ion

A carboxylate anion and a positive ion forms a

carboxylate salt

sodium propanoate


Groups6

Groups

Group name: ester

Found in:esters

methyl propanoate

( could also be written: CH3OOCCH2CH3 )

Notice how each side of the ester is named:

methyl

propanoate


Groups7

Groups

Group name: amine

Found in:amines

butan-2-amine

( could also be written: CH3CH(NH2)CH2CH3 )


Groups8

Groups

Group name: amide

Found in:amides

don’t need to name these

( could also be written: CH3CONHCH2CH2CH3 )
