- Carbon–carbon bond dissociation enthalpies have been measured for many alkanes. Identify the alkane in each of the following pairs that has the lower carbon–carbon bond-dissociation enthalpy, and explain the reason for your choice. (a) Ethane or propane (b) Propane or 2-methylpropane (c) 2-Methylpropane or 2,2-dimethylpropane (d) Cyclobutane or cyclopentaneStereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of trans-1,2-dibromocyclobutane.(Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.)Use the wedge/hash bond tools to indicate stereochemistry where it exists.In cases where there is more than one answer, just draw one.Name the following compounds include stereochemistry.
- 2. (a) The heat of combustion of liquid benzaldehyde (C6H5CHO) is -3393 kJ/mole, and that of liquid 2,4,6-cycloheptatrien-1-one (C₂H6O) is -3470 kJ/mole. Assume that both combustions result in products, CO2 and H₂O, that are entirely in the gas phase. Using the standard chemical equation for the combustion of a hydrocarbon, find the heats of formation (in kJ/mol) for both benzaldehyde and 2,4,6-cycloheptatrien-1-one in the liquid phase. (b) Consider the isomerization from 2,4,6-cycloheptatrien-1-one to benzaldehyde. What is the enthalpy change (in kJ/mol) for this reaction? Is it endothermic or exothermic? (c) If ArxnS = -18 J/mol-K for the isomerization reaction, find ArxnG at 350 K (in kJ/mol) and determine if it is spontaneous in the liquid phase at this temperature. For this calculation, you may assume that ArxnH and ArxnS are constant between 300 and 350 K.Ball-and-stick models for four hydrocarbons that each contain six carbon atoms per molecule are shown below. Rank these compounds in order of decreasing Sº values (all are liquids under standard conditions).For the hydroxyl rotation of vinyl alcohol, which conformation (1 or 2) would be more stable and why?
