How many different aldols (β-hydroxyaldehydes), including constitutional isomers and stereoisomers, are formed upon treatment of butanal with base?
How many different β-hydroxyaldehydes and β-hydroxyketones, including constitutional isomers and stereoisomers, are formed upon treatment of a mixture of butanal and acetone with base?
Arrange the acids HOBr, HBrO3 and HBrO2 in order of increasing acid strength, and explain why.
Problem- Show how free-radical halogenation might be used to synthesize the following compounds. In each case, explain why we expect to get a single major product.
why is the experimental mole ratio of Cu/O not exactly a whoe number. Think of what may have happened to the copper during the drying period, and what effect this would have on the calculated values
Calculate the wavelength, in naniometers, of the spectral line produced when an electron in a hydrogen atom undergoes
a gaseous sample of a compound has a gas density of 0.977 gl at 710.0 torr and 100.0 c. what is the molar mass the
The average speed of a nitrogen molecule at 20oC is 515 m/sec. How many minutes will it take the nitrogen molecule to cover exactly 20 km?
The vapor pressure of benzene is 100 mmmHg at 26.1 C. Calculate the vapor pressure of a solution containing 26 g of camphor (C10H16O) dissolved in 98.5g of benzene. (Camphor us a low-volality solid.)
Gycine (C2H5O2N) is important for biological energy. The combustion of glycine is given by the equation- 4C2H5O2N (s) + 9O2 (g) -------> 8CO2(g) + H2O(l) + 2N2 (g)
Researchers analyzing an unknown hydrocarbon with chemical formula CxHy found that 225 grams of O2(g) were required for complete combustion of 1.0 mol CxHy, to form CO2(g) and H2O(g) only. Unfortunately, a faulty valve between the furnace and abso..
2-Methyl-1-propanol is more soluble in water than is glycerol because 2-methyl-1-propanol forms fewer hydrogen bonds with water. Glycerol is more soluble in water than is 2-methyl-1-propanol because glycerol can form multiple hydrogen bonds with wate..
For each of the rate laws below, what is the order of the reaction with respect to the hypothetical substances X, Y, and Z? What is the overall order?
