Chapter 8, Problem 83GQ
Dihydroxyacetone is a component of quick-tanning lotions. (It reacts with the amino acids in the upper layer of skin and colors them brown in a reaction similar to that occurring when food is browned as it cooks.)
- (a) Use bond dissociation enthalpies to estimate the enthalpy change for the following reaction. Is the reaction exothermic or endothermic?
- (b) Are dihydroxyacetone and acetone polar molecules?
- (c) A proton (H+) can be removed from a molecule of dihydroxyacetone with strong bases (which is in part what happens in the tanning reaction). Which H atoms are the most positive.

- Since the heat of reaction is negative, why isn't the heat of reaction negative for octane, too? Is it because the heat of reaction for octane is before the reaction takes place, and hence before the release of heat? Is this the reason why octane's heat is positive, while the reaction as a whole is negative? Because it must have to do with the conservation of energy. Perhaps the reaction is the system, and octane is part of the surroundings, hence the opposite signs?arrow_forwardCalculate the following: Standard enthalpy of formation of methane, the enthalpy of atomization of methane and the Bond energy term for the C-H bond.arrow_forwardestimate the enthalpy change for the following reaction:CH3OH(g) + HI(g)CH3I(g) + H2O(g)arrow_forward
