2. Alkanes contain only bonds between carbon atoms.
3. The suffix used for naming alkanes is .
4. A group is an alkyl group attached to the main chain.
1. Which of the following is the correct IUPAC name for CH₃CH(CH₃)CH₂CH₃?

1. Draw the condensed structural formula for 3-ethyl-2,4-dimethylhexane.
2. Name the following alkane according to IUPAC rules:
CH₃-CH₂-CH(CH₃)-CH₂-CH(CH₃)-CH₃
1. When numbering the carbon chain, you should start from the end that gives the substituents the lowest possible numbers.
True
False
2. The prefixes 'di-', 'tri-', 'tetra-' are used to indicate the number of different types of alkyl groups.
True
False
Match the alkane name with its corresponding number of carbon atoms in the parent chain.

2. Propane
b. 1 carbon
3. Pentane
c. 3 carbons
4. Octane
d. 8 carbons
