(a)
Interpretation: The heat of combustion per gram needs to be determined for the mentioned hydrocarbons.
Concept Introduction: The heat of combustion is calculated generally in unit kcal/mol. To convert it into kcal/g, the value needs to be divided with the mass of substance in its 1 mol.
(b)
Interpretation: The same calculations as in part (a) needs to be done for ethanol.
Concept Introduction: The heat of combustion is calculated generally in unit kcal/mol. To convert it into kcal/g, the value needs to be divided with the mass of substance in its 1 mol.
(c)
Interpretation: Whether the fuel capability of hydrocarbon is more or less than ethanol needs to be determined.
Concept Introduction: The heat of combustion is calculated generally in unit kcal/mol. To convert it into kcal/g, the value needs to be divided with the mass of substance in its 1 mol.

- 6-23 We dissolved 0.32 g of aspartic acid in 115.0 mL of water and obtained a clear solution. After it stands for two days at room temperature, we notice a white powder at the bottom of the beaker. What may have happened?arrow_forwardUsing differences in C-H bond dissociation energies, calculate approximate selectivities secondary vs primary halogenation for the following compouond at 0o C. Be sure to include numberical differences.arrow_forwardhelp please use sig figs 8 thanksarrow_forward
- Table 6.4. Oxidation: Reaction with Baeyer’s reagent (cold, dilute, neutral, aqueous KMnO4) Write (+) if the reaction is positive, (-) if negative. SAMPLE OBSERVATIONS +/- cyclohexane cyclohexene benzene toluene acetylene Enumerate the classes of hydrocarbons that are oxidizable by Baeyer’s reagent. ________________________________________________________________________ ________________________________________________________________________ What is the structural feature of these classes of hydrocarbons? ________________________________________________________________________ ________________________________________________________________________arrow_forwardGive a clear handwritten answer of all reactions sub parts product.....?arrow_forwardDo the reactions and he explains why.arrow_forward
- Based on the general procedure given and reaction scheme, which is the limiting reagent and what is the equivalence?arrow_forwardThe aerobic oxidation of para-xylene to terephthalic acid is an important process in industrial chemistry. Discuss why the oxidation of the second methyl group requires harsher conditions than the oxidation of the first methyl group.
