Organic Chemistry Nomenclature

Naming

# of carbons
1=meth- 2=eth= 3==prop- 4==but- 5=pent- 6=hex- 7=hept 8=oct- 9=non- 10=dec -

Position of double/triple bond

Number of double/triple bond

Alkyl groups

Sufix(Functional group)

Carboxylic acid=-oic acid Ester=-onate Amide=-Amide Aldehyde=-al Ketone=-one Alcohol=-ol Amide=-Amide Hydrocarbon =-e

Alkane=an Alkene=en Alkyne=yn

Special benzenes Benzene Toluene Phenol

Cyclo if ring shaped

Hydrocarbons

Alkane
sp3 hybridized Ex: ethane

Note: very non polar due to weak delta positive hydrogen

Cyclic Alkane
Carbon chain forms a ring Ex: cyclohexane
Benzene
Carbon chain forma a ring with three double bonds and a graphene layer Ex:methylbenzene
Alkene
sp2 hybridized Ex: ethene

Shapes Cis: larger functional groups on same side of double bond Trans: larger functional groups on opposite side of double bond

Alkyne
sp hybridized Ex: ethyne

Contains oxygen

Adehyde Contains carbonyl group Oxidation of primary alcohol Ex: Ethanal
B.P Carboxylic acid> Alcohol> Aldehyde/ Ketone/ Ester> Ether
Ketone Contains carbonyl group Oxidation of secondary alcohol Ex: ethanone
Carboxylic acid Contains carboxylic group Oxidation of aldehyde Ex: ethanoic acid
Ester Alcohol+carboxylic acid Fruity smell Ex: ethyl acetate
Alcohol Contains one or more hydroxyl groups Ex: ethanol
Tertiary

C with OH has three C-C bonds

Secondary

C with OH has two C-C bonds

Primary

C with OH has one C-C bond

Ether Two hydrocarbon groups linked by an oxygen Ex: ethoxyethane

Contains nitrogen

Amine Nitrogen attached to the carbon group Has a bad smell Ex: trymethylamine
Amide Amine+Carboxylic acid Ex: methanamide

Important Name all identical chains at once Order alphabetically

position on main chain

Number of functional group
Side chain suffix

Functional groups NH2=amino OH=hydroxy NO2=nitro Benene=phenyl Alkane= #C+yl Ester=#C+yl Ether=#C+oxy Br=bromo Cl=Chloro F=fluoro I=Iodo

# of carbons 1=meth- 2=eth= 3==prop- 4==but- 5=pent- 6=hex- 7=hept 8=oct- 9=non- 10=dec -

If ring shaped, cyclo

2=di 3=tri 4=tetra 5=penta 6=hexa 7=hepta 8=octa 9=nona 10=deca
"#-" "#,#-" "#,#,#-" etc...
If nitrogen is present "N-" "N,N-" "N,N,N-" etc

Chain with lower IUPAC priority

IUPAC naming priorities

Carboxylic acid Ester Amide Aldehyde Ketone Alcohol Amine Alkene Alkyne Alkane Ether Alkyl Halide
Longest chain= main chain
Highest priority=main chain Rest= side chain

Types

Tertiary Three C-N Bonds on N

Secondary Two C-N Bonds on N

Primary One C-N Bond on N

Chains

CIS (Z) TRANS (E)

If double bonded Isomer
Side chain

No space Exception: ester

Main chain

Chain with higher IUPAC priority
