Problem- Discuss the reasoning why the aldol reaction product was produced in such a high yield. For full credit be sure to include factors relating to equilibrium, intermediate and product stability and other potential factors
Comment on the mechanism and irreversibility of the Diels-Alder reaction of the benzyne reaction with tetraphenylcyclopentadienone. Be sure to include topics such as diene/dienophile electronics, equilibrium and any other potentially significant reasons t
Answer all three questions and provide required steps
What is the temperature (in C) of a 0.536g sample of neon gas, Ne(g), that occupies a 500.0mL container at a pressure of 762.3 mmHg
500.0mL of 0.150 M NaOH is added to 575mL of 0.200 M weak acid (Ka = 8.20 × 10-5). Explain what is the pH of the resulting buffer
A carbon-carbon bond requires 348kj/mol to break. What is the longest wavelength of radiation with enough energy to break carbon-carbon bonds?
The forensic technician at a crime scene has just prepared a luminol stock solution by adding 20.0 g of luminol to rm H_2O creating a solution with a total volume of 75.0 rm mL.
Chemistry of Proteins and Hemoglobin - What is the effect of the following changes on the O 2 affinity of hemoglobin?
Which alkene is more stable, the E or Z isomer above. why does irradiation go from E to Z rather than the other way around. how will the Rf values from TLC compare
Question- Predict the main/most stable di-nitration product of benzil and draw a mechanims for how the product formed. 1) Would you expect this di-nitration product to above or below the desired product spot (benzil) on a TLC plate
A reaction has a rate constant of 0.00117 s^-1 at 400 k and 0.689s^-1 at 450 k.1- Calculate the activation energy (Ea) and the pre- exponential factor (A) for this reaction. 2- what is the value of the rate constant at 425k
The observations listed were made on different solns. Given the observations state which ion studied in this experiment is present. If the test is not definitive, indicate that with a (?).
Problem- Calculate the pH at the equivalence point for the titration of 0.160 M methylamine (CH3NH2) with 0.160 M HCl. The Kb of methylamine is 5.0Ã- 10â€"4.
Determine the molar ratio of sodium borohydride to 9-fluorenone that you used in the experiment.
Problem- Robinson predicted a carbocation intermediate in the addition reaction of an alkene and Cl2. Is there experimental evidence that contradicts this mechanism
