Question
Which of the following represents a straight chain hydrocarbon?
The correct answer is
Butane
Identifying Straight Chain Hydrocarbons
A straight chain hydrocarbon is an organic molecule where carbon atoms are linked together in a continuous, unbranched chain. Let's analyze the options to find the one that fits this definition.
Option Analysis
- Isobutane: This is an isomer of butane but has a branched carbon chain structure.
- Cyclopentane: This is a cyclic hydrocarbon, meaning the carbon atoms form a ring.
- Butane: This is an alkane with the formula C4H10. Its structure consists of four carbon atoms linked in a single, continuous chain (CH3-CH2-CH2-CH3). This is a straight chain hydrocarbon.
- Benzene: This is an aromatic hydrocarbon with a ring structure (C6H6).
Conclusion
Based on the structural analysis, Butane is the only molecule among the options that represents a straight chain hydrocarbon.
