|Section2= |Section3= }} Methylcyclohexane is a simple organic hydrocarbon with a molecular formula is C7H14; it is a colourless liquid with a faint benzene-like odor. Methylcyclohexane is used as a solvent and occasionally as a reagent in organic synthesis and polymer chemistry. It is a component of jet fuel and is used in some consumer products such as correction fluids. It can be handled safely, but is considered a flammable and toxic liquid with consequences in case of human or other environmental exposure. ==Structure and conformation== (詳細はcyclohexane because it has one branching via the attachment of one methyl group on one carbon of the cyclohexane ring. Like all substituted cyclohexanes, it can interconvert rapidly at ambient and higher temperatures between two chair conformers. However, the lowest free energy form of this monosubstituted methylcyclohexane occurs when the methyl group occupies an equatorial rather than an axial position. In the axial position, the methyl group experiences steric crowding (steric strain) because of the presence of axial hydrogen atoms on the same side of the ring (known as the 1,3-diaxial interactions). There are two such interactions, with each pairwise methyl/hydrogen combination contributing approximately 7.61 kJ/mol of strain energy. The equatorial conformation experiences no such interaction, and so it is the energetically favored conformation. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Methylcyclohexane」の詳細全文を読む スポンサード リンク
