Isopentane has a higher diffusivity than does n-pentane. This is attributed to the higher cross section of isopentane, which is closer to the void cross section. Further, the coupling of the translational motion with the slower dihedral angle reorientation in the case of n-pentane decreases its...
Neopentane burns most intensely, followed by isopentane, and finally n -pentane. A faster heating rate will be accompanied by more intense spontaneous combustion of n -pentane and more product formation, which will cause greater harm to the surrounding area. Thus, in order to reduce the ...

Feasibility has been established for complexing n-pentane with urea and the use of this method to extract n-pentane from its mixtures with isopentane. The resulting complex is characterized by weak bonds between components. Optimal conditions have been determined, giving the greatest degree of ...
The heats of combustion of the isomeric pentanes have been measured in the gaseous state at 25°C and 1 atm pressure in a flame calorimeter: ΔHoc(n-pentane, g)=–844·99±0·23 kcal mole–1, ΔHoc(isopentane, g)=–843·31±0·22 kcal mole–1, ΔHoc(neopentane, g)=–839·88...
