IB Chemistry Organic Naming Assignment
Name:_________________________
1. Name each of the following organic compounds using IUPAC naming rules. You will have to use
the functional groups to determine the class of chemical prior to naming. (8 marks)
a) CH3CH2CHBrCH3
e) CH3CH2CHCHCH2CH2CH3
b) CH3CH2COCH2CH3
f)
c)
g) COOH-CHCl-CH2-CHCl-CH2-CHBr-CH(CH3)-CH3
d)
h)
*Each bend is a carbon
*Where each line ends is a carbon
2.
Please draw the chemical structure for each of the organic names given. Please use complete
structural diagrams showing all atoms and bonds.
a) 2-methylbutane
e) Benzene (see notes)
b) 3-bromobutanone
f) 6,7-diethyl-2,4-dimethylnonane
c) 2,3,4-trimethylpentanal
g) 2-bromo-5-fluoro-3-hexyne
d) Ethanoic acid
f) 2-propanol
3.
Draw an example of a secondary alcohol and provide the correct IUPAC name for the
compound. (3 marks)
4. Carboxylic acids generally have higher boiling and melting points than aldehydes and ketones of
comparable chain length. Explain why this is observed in organic chemistry. (2 marks)
5. Explain why ethanol has a lower boiling point than hexanol. (2 marks)
6. Draw and name the 3 structural isomers of pentane. (6 marks)
