Problem: Gasoline is composed primarily of hydrocarbons, including many with eight carbon atoms, called octanes. One of the cleanest-burning octanes is a compound called 2,3,4-trimethylpentane, which has the following structural formula. The complete combustion of one mole of this compound to CO 2(g) and H2O(g) leads to ΔH° = -5064.9 kJ/mol. (c) By using the information in this problem and data in Table 5.3, calculate ΔHf° for 2,3,4-trimethylpentane.
