1.) Which form of molecule A is the most stable (1, 2, or 3)? Provide a graphical (i.e. figures not graphs) provide an explanation for your answer.
2.) Enamines are generally reactive toward electrophiles. For example, compound E reacts with HBr at room temperature. Surprisingly, enamine F is unreactive with HBr even at 150 °C. Provide a rationale forthis difference in reactivity.
3.) The cis isomer of 1,2-azodifluoride (below) is more stable than the trans isomer by 3 kcal/mol. Explain this difference.
the reaction of a particular alcohol with a carboxylic acid is 3.83. What is the calculated yield of the ester?
One mole of N2, one mole of O2, and 0.5 mol of H2 are at 25 oC and 1 atm. The final total pressure of the mixture is 1 atm. Calculate delta_S on forming the mixture.
if equal masses of N2 and H2 (7.00 grams each) are combined to produce ammonia NH3, how many grams of ammonia could be produced at maximum yield?
in general chemistry you learned thatoxidation meant any reaction which involves loss of electrons butin organic

Consider a particle in a one-dimensional box, the longest transition wavelength for the particle is 200 nm. What is the transition wavelength if the mass of the particle is doubled
What would be the formula for the compound sample If a sample of a compound contains 1.36 mol of nitrogen atoms and 2.72 mol of oxygen atoms?
A solution is prepared by mixing 85.0 mL of 5.00 M HCl and 25.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
Suppose want to measure the iron content of a sample of water run-off. A 25.0 mL sample was acidified with nitric acid and then treated with excess KSCN to form a red complex that can be analyzed with spectroscopy. The solution was then diluted to 10..
