Constitutional Isomers of Compound C₆H₁₄

Which structures represent the constitutional isomers of the compound with the molecular formula C₆H₁₄?

A. Hexane
B. 3-Methyl pentane
C. 2-Methyl pentane
D. Cyclohexane

Answer:

The constitutional isomers of the compound with the molecular formula C₆H₁₄ are:
- Hexane
- 3-Methyl pentane
- 2-Methyl pentane

To identify the constitutional isomers of the compound with the molecular formula C₆H₁₄, we need to examine the structural arrangements of the carbon and hydrogen atoms. Multiple structures may represent constitutional isomers of the given compound.

The molecular formula C₆H₁₄ indicates that the compound contains 6 carbon atoms and 14 hydrogen atoms. To identify constitutional isomers, we must consider the different ways these atoms can be arranged while maintaining the same molecular formula.

Given that the molecular formula C₆H₁₄ represents an alkane, we can eliminate structures with double or triple bonds. We can also rule out cyclic structures since the formula suggests an acyclic arrangement. Based on these considerations, potential constitutional isomers include:

Hexane: A straight-chain alkane with the formula C₆H₁₄.
2-Methylpentane: An alkane with a branched structure, where one of the carbon atoms in the main chain is substituted by a methyl group.
3-Methylpentane: Another alkane with a branched structure, where a different carbon atom in the main chain is substituted by a methyl group.

These three structures represent the constitutional isomers of the compound with the molecular formula C₆H₁₄.
