What is the name of the alkane CH₃–CH₂–CH₂–CH₂–CH₂–CH₂–CH₃?
TL;DR
Heptane, C₇H₁₆, a straight-chain alkane with seven carbon atoms — option 4.
Question
Name the compound: CH₃–CH₂–CH₂–CH₂–CH₂–CH₂–CH₃.
Answer choices
- Hexane.
- Nonane.
- Decane.
- Heptane.
Answer
Heptane, C₇H₁₆ — option 4.
Explanation
The formula contains two terminal CH₃ groups and five CH₂ groups between them: seven carbon atoms in total.
All carbon–carbon bonds are single bonds, so the compound is an alkane. The straight-chain alkane with seven carbon atoms is heptane. The general formula CₙH₂ₙ₊₂ confirms C₇H₁₆.
