Problem- Hydrochloric acid is about as strong a mineral acid as sulfuric acid. Why would HCl not be satisfactory catalysts in this reaction?
Working it out this problem
The Diels-Alder reaction between butadiene also dimethyl maleate yields a ring structure. Depict the structure and indicate the stereochemistry of the new stereocenters
How would you separate laurie acid from alpha-naphtol. lauric acid is soluble in cyclohexane, but what would be done after this is added? Decanting then heating
illustrate the decomposition of arenediazonium salts using a reaction mechanism and briefly explain why the decomposition produced formed is so reactive.
A football is inflated to a pressure of 1.00 x 10^3 torr in a room at 25 degrees C. If the game is played at 10 degrees C, what will the pressure in the ball be, neglecting any volume change in the ball and assuming that it doesn't leak?
Problem- A student observed that enzyme solutions (without fluoride ions added to it) turn red fairly rapidly at room temperature. What does this phenomenon suggest that is also present in the enzyme extract beside the enzyme
Explain how many moles of HF (Ka=6.8x10-4) should be added to water to form 0.230L of solution with a pH of 3.50
How many milliliters of 4.21 M NaOH are needed to completely neutralize 76.9 mL of 0.340 M H3PO4?
Coniine, a toxic substance isolated from a poison hemlock, contains only carbon, hydrogen, and nitrogen. Combustion analysis if a 5.024mg sample yields 13.90mg of CO2 and 6.048mg of H2O. What is the empirical formula for Coniine
Barium sulfate, BaSO4, is used in medical imaging of the GI tract because it is opaque to X rays. A barium sulfate solution, sometimes called a cocktail, is ingested by the patient
The carbonyl peak of benzaldehyde appears as a very strong and intense peak at 1703 cm -1. Normally the carbonyl peak of an aldehyde appears at 1725 cm -1. Why does the carbonyl peak of benzaldehyde appear at a lower frequency
Acetaminophen was reacted with K2CO3 and iodoethane to yield phenacetin. Would a similar reaction take place if cyclohexanol, K2CO3, and iodoethane were mixed together. Explain.
