2,2-Dimethylbutane

Description:
2,2-Dimethylbutane is a branched-chain alkane with the molecular formula C₈H₁₈. It is characterized by its four-carbon backbone with two methyl groups attached to the second carbon atom. This structure contributes to its unique physical and chemical properties. 2,2-Dimethylbutane is a colorless, flammable liquid at room temperature, with a relatively low boiling point compared to straight-chain alkanes of similar molecular weight. It is insoluble in water but soluble in organic solvents, making it useful in various applications, including as a solvent and in fuel formulations. The compound exhibits typical alkane reactivity, primarily undergoing combustion and substitution reactions. Its branched structure results in lower density and higher octane ratings compared to its straight-chain isomers, making it a valuable component in gasoline. Additionally, 2,2-Dimethylbutane has a relatively low vapor pressure, contributing to its stability under standard conditions. Safety precautions should be observed when handling this substance due to its flammability and potential health hazards upon inhalation or skin contact.
