2. Substituents are named by changing the -ane ending of the corresponding alkane to .
3. The prefix for an alkane with 5 carbon atoms is .
4. What is the correct IUPAC name for a straight-chain alkane with 7 carbon atoms?
Heptane
Hexane
Octane
Pentane
5. Which of the following is an incorrect IUPAC name?
2-methylpropane
3-ethylpentane
2,2-dimethylbutane
