“Gasohol,” a mixture of gasoline and ethanol, C2H5OH, is used as automobile fuel. The alcohol releases energy in a combustion reaction with O2.
If 0.115 g ethanol evolves 3.62 kJ when burned at constant pressure, calculate the combustion enthalpy for ethanol.

- 2. Consider the following intramolecular aldol condensation. This result is fully consistent with the two rules we use to determine the likely product of intramolecular aldol condensation reactions. Rule 1: Only form 5 or 6 membered rings, rule 2: the less- hindered carbonyl group will serve as the electrophile. OH- H₂O product not formed Interestingly, if the same starting material is treated with a secondary amine such as pyrrolidine and some acid, the other product is formed preferentially. Describe the mechanism for what is happening in the presence of amine and acid. (6 points)arrow_forwardDraw the structure of ,-diethyl--propylthiopentane. With explanationarrow_forwardA. Provide a stepwise mechanism for the formation of nerolidyl pyrophosphate fromfarnesylpyrophosphate B. Provide a stepwise mechanism for the formation of carbocation 1 from nerolidylpyrophosphate. Number the backbone carbons of nerolidyl pyrophosphate from 1 to 11 as shown, andinclude the carbon numbering in your structure of 1 C. Following from B, give an arrow-pushing mechanism to convert 1 to 2 and 2 to 3. Use thebackbone carbon numbering from 1 to indicate where carbon atoms ended up in 2 and 3 D. In addition to forming epi-cedrol, carbocation 3 gives three minor byproducts: a diastereomericalcohol and two alkenes. Draw mechanisms that could give rise to these three productsarrow_forward

Draw electron-flow arrows on the structure on the left to indicate how the electrons reorganize to give the structure on the right. Interactive 3D display mode CH₁₂ Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP. CONT を口か H3C. CH3 H C Zo S CI Br P9 Farrow_forward
