Depict structures of the organic starting material as well as product formed for the reduction of vanillin acetate (4-formyl-2-methoxyphenyl acetate C10H10O4) by sodium borodeuteride (NaBD4) reduction. Star(*) all chirality centers. Explain what R/S configuration results at the carbinol (C-OH) position of the product? (Explain what functional groups are reduced by this hydride reagent?)
what is the pH of the mixture without considering the ionic strength effect? Sulfathiazole reacts in part with NaOH to give sodium sulfathiazole. The pKa of sulfathiazole is 7.12.
what is the boiling point at 1.000 atm pressure of a solution of 1.50 mol of nacl dissolved in 1.00 kg of water
question a reverse osmosis unit is used to obtain drinkable water from a source that contains 0.870 g nacl per liter.
explain why does atp synthesis occur in the presence of rotenone an inhibitor of one the reactions in the electron
Explain the rate law for the solvolysis of benzyl bromide in 50% ethanol/50% water at room temperature (24C) is given by: rate = 2.9 x 10-5 (benzyl bromide)(OH-) + (benzyl bromide)
what is a detailed mechanism for the formation of dibenzalacetone? This reaction is beginning with acetone and benzaldehyde and is treated with NaOH and then forms dibenzalacetone.
Calculate the rate constant and half- life for the radium decay. Starting with 1.0 g of the radium sample, what is the activity after 500 years? The molar mass of ra-226 is 226.03 g/mol.
n basic solution it gives ClO3- and ClO2- ions. 2ClO2(aq) + 2OH-(aq) ? ClO3-(aq) + ClO2- (aq) + H2O. To obtain the rate law for this reaction, the following experiments were run and, for each, the initial rate of the reaction of ClO2
A perfect sphere of aluminum metal with a diameter of 4.56x10^-2 m reacts with 3.80L of 5.25M hydrochloric acid. the products are an aluminum chloride solution and hydrogen gas.
