2a and 2b **Concept Questions****Predict the Product.** Provide the stable organic product(s) for the reactions below.1. The top reaction: - **Reactants:** - Left: Cyclohexane-1,3-dione with a methyl group at one of the dione carbons. - Right: Propylamine (1 equivalent). - **Steps:** - 1. 1 eq. Propylamine (NH₂) - 2. H₂O / HCl2. The second reaction: - **Reactants:** - Left: Acetyl chloride (ethanoyl chloride). - Right: Tetrahydrofuran-2-ol. - **Steps:** - 1. Pyridine3. The third reaction: - **Reactants:** - Left: 2-aminophenol. - Right: Diketene (excess). - **Steps:** - 1. Diketene (excess) - 2. H₂O4. The bottom reaction: - **Reactants:** - Left: 1,3-benzodioxole-4,5-dione. - Right: Piperazine (1 equivalent). - **Steps:** - 1. 1 eq. Piperazine (NH₂) - 2. H₂O / HCl---In each of the above reactions, the stable organic products formed will depend on the interaction between the reagents and their functional groups, along with the reaction conditions specified. - The first reaction typically results in the formation of an imine due to the reaction of a ketone and amine, followed by hydrolysis in acidic conditions.- The second reaction is an esterification reaction facilitated by pyridine which may result in the formation of an ester.- The third reaction involves the formation of a lactam when diketene reacts with 2-aminophenol and water hydrolyzes it.- The fourth reaction may produce a hydroxamic acid through reaction with piperazine followed by hydrolysis.Detailed mechanisms and exact product structures would require drawing tools and a step-by-step mechanistic description.

) During the last 30 years of rapid development in space exploration, many different rocket fuels have been tried. Two of these fuels are hydrogen and dimethylhydrazine. The equations for the reactions of these fuels are: 2H2(g) + O:(g) → 2H2O(1) (CH:);N2H2(g) + 40:(g) N2(g) + 4H>O(g) + 2CO:(g) AH = -576 kJ n I. AH =-1694 kJ moi II. Which fuel releases the greater amount of energy per gram? Show your working.

The chart shows average CO2 emissions for fossil fuel vehicles (gasoline, diesel, and hybrid gas‑electric), as well as electric vehicles. The ordinate is mg CO2 per mile driven per pound mass of the vehicle (called curb weight). For electric vehicles, CO2 emission varies in U.S. states because of the mix of fuels used to generate electricity. If electricity came entirely from solar power, there would be little CO2 associated with its production. California has the lowest CO2 emission for producing electricity and Ohio has the highest because it depends heavily on coal‑fired power plants. The chart does not include CO2 emission from manufacturing vehicles. When normalized for distance driven by each kind of vehicle before it is scrapped, CO2 emission associated with manufacturing electric vehicles is estimated to be 25–75% greater than CO2 emission associated with manufacturing gasoline and diesel vehicles. If manufacturing were included, CO2 emission associated with electric vehicles…

10 Ethylene (CH,CH,) is the starting point for a wide array of industrial chemical syntheses. For example, worldwide about 8.0 × 10° kg of polyethylene are made from ethylene each year, for use in everything from household plumbing to artificial joints. Natural sources of ethylene are entirely inadequate to meet world demand, so ethane (CH,CH,) from natural gas is "cracked" in refineries at high temperature in a kinetically complex reaction that produces ethylene gas and hydrogen gas. Suppose an engineer studying ethane cracking fills a 25.0 L reaction tank with 20.0 atm of ethane gas and raises the temperature to 650. °C. He believes =0.040 at this temperature. K,= Calculate the percent by mass of ethylene the engineer expects to find in the equilibrium gas mixture. Round your answer to 2 significant digits. Note for advanced students: the engineer may be mistaken about the correct value of K, and the mass percent of ethylene you calculate may not be what he `p' actually observes.
