Multiple Choice QuestionAll of the following names correspond to alkanes except ______.Multiple choice question.octane2-methylheptane1-octene2,3-dimethylhexane

Break Down the Problem

1. Identify the structure of each compound listed in the options.
2. Determine which of the listed names does not correspond to an alkane, which is defined as a saturated hydrocarbon with only single bonds.

Relevant Concepts

• Alkane Definition: Alkanes are hydrocarbons with the general formula $C_nH_{2n+2}$, meaning they contain only single bonds between carbon atoms.
• Identification of Alkenes: Compounds containing carbon-carbon double bonds (like an alkene) will not qualify as alkanes.

Analysis and Detail

1. octane: This is a straight-chain alkane with 8 carbon atoms $(C_8H_{18})$.
2. 2-methylheptane: This is also an alkane, derived from heptane (7 carbon atoms) with a methyl group added, thereby maintaining the single bond structure.
3. 1-octene: This is an alkene, not an alkane, as it contains a carbon-carbon double bond.
4. 2,3-dimethylhexane: This is an alkane, derived from hexane (6 carbon atoms) with two methyl groups added.

Verify and Summarize

From the analysis above, the only compound that does not correspond to an alkane is 1-octene, since it contains a double bond.

Final Answer

1-octene
