Solution: Three common hydrocarbons that contain four carbons are listed here, along with their standard enthalpies of formation:HydrocarbonFormulaΔH˚f(kJ/mol)1,3-ButadieneC4H6(g)111.91-ButeneC4H8(g)1.2n-Butane

Problem
Three common hydrocarbons that contain four carbons are listed here, along with their standard enthalpies of formation:
HydrocarbonFormulaΔH˚f(kJ/mol)
1,3-ButadieneC4H6(g)111.9
1-ButeneC4H8(g)1.2
n-ButaneC4H10(g)–124.7

For 1,3-Butadiene, calculate the fuel value in kJ/g.
