Abstract
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: ΔHo c(n-pentane, g)=–844·99±0·23 kcal mole–1, ΔHo c(isopentane, g)=–843·31±0·22 kcal mole–1, ΔHo c(neopentane, g)=–839·88±0·23 kcal mole–1. These results were used to derive the heats of formation of each of the pentanes. The heats of isomerization of the pentanes have been discussed in terms of the Allen bond-energy scheme.Keywords
