What is the molecular structure of 3,4-dimethylhexane and how does it contribute to its chemical properties?

The molecular structure of 3,4-dimethylhexane consists of a chain of six carbon atoms with two methyl groups attached at the 3rd and 4th positions. This structure results in a branched molecule with a more compact shape compared to straight-chain hexane. The branching reduces intermolecular forces, leading to lower boiling points and higher volatility. Additionally, the branching increases the molecule's resistance to oxidation and combustion, making it more stable and less reactive compared to straight-chain alkanes.
