Compounds 1 and 2 were prepared, and the difference in their heats of combustion was found to be 17.2 kJ/mol (J. Am. Chem. Soc. 1961, 83, 606-614): H H 1 Shown below are the lowest-energy conformations of compounds 1 and 2. Identify which drawing matches which compound, and identify which compound has the larger heat of combustion. H H H H |||I 2 H 4 H H The first drawing is compound 1, and compound 1 has a larger heat of combustion because it is the less stable compound. O The first drawing is compound 2, and compound 2 has a larger heat of combustion because it is the less stable compound. The first drawing is compound 2, and compound 2 has a larger heat of combustion because it is the more stable compound. The first drawing is compound 1, and compound 1 has a larger heat of combustion because it is the more stable compound.
