An important characteristic in the fischer esterification mechanism is the formation of a tetrahedral intermediate which is the result of
a. the alcohol attacking the 2-phenylacetic acid with the subsequent loss of a proton.
b. protonation of the ethanol by H2SO4.
c. protonation of the carbonyl oxygen of the 2-phenylacetic acid.
d. protonation of the hydroxyl group of the 2-phenylacetic acid.
The elements contained in acetylsalicyic acid are hydrogen, carbon, and oxygen. The combustion of 3.000 g of the pure compound yields 1.200 g of water and 3.72 L of dry carbon dioxide, measured at STP
Give two reasons why a 100% yield is not obtained in actual chemical manufacturing processes.
If you mix 50mL of 0.34M HCN with 100mL of 0.17M KOH what is the pH of the resulting solution. (Ka=4.0 x 10^-10)
Assuming that you start with 2.00 g of sodium benzoate and 5 mL of 3 M HCl, and assuming that the reaction proceeds to form benzoic acid, what would your theoretical yield be? use two decimal places
According to the Rydberg equation, what is the wavelength (in m) of photons produced by a transition from n = 5 to n = 3 in hydrogen atoms. Enter the number in exponential format
A container (8.65-L ) holds two gases mixture at 31 °C. The partial pressures of gas X and gas Y, respectively, are 0.206 atm and 0.867 atm. If 0.200 mol a third gas is added with no change in temperature or volume determine the total pressure be..
Calculate the equilibrium constant for the reaction. The standard enthalpy change delta H, for a strong acid-strong base reaction is -57.8k J. Determine the standard entropy change delta S for the reaction at 25 degrees C.
How much heat is needed to convert 923 g of ice at -30°C to steam at 119°C. (The specific heats of ice, steam, and liquid are 2.03 J/g · °C, 1.99 J/g · °C, and 4.18 J/g·°C, respectively. The heat of fusion is 6.02 kJ/mol and heat of vaporization i..
Consider two cells, the first with Al and Ag electrodes, and the second with Zn and Ni electrodes, each in appropriate 1.00M solutions of their ions.
What is the density of a block of marble that occupies 253 cm3 and has a mass of 752 g?
The refining of aluminium from bauxite ore proceeds by the overall reaction: 2Al2O3 + 3C --> 4Al + 3CO2.
There are several reagents that can be used to effect addition to a double bond including: acid and water, oxymercuration-demercuration reagents, and hydroboration-oxidation reagents
