An attempt to prepare 1-(3-nitrophenyl)butan-1-one from nitrobenzene, butanoic acid chloride and AlCl3 would fail. Friedel-Crafts alkylation and acylation reactions won't work because of the deactivating nitro group present on the benzene ring. Propose an alternate pathway to the ketone product desired. Would the proposed reaction mechanism result in ortho and para substituted products along with the desired meta form?
what volume of 3M sulphuric acid is required to neutralize all of the C 7 H 5 NaO 3 and the excess sodium hydroxide present after the initial reaction? Determine how much H 2 SO 4 was in excess?
Calculate the hypothetical retention times for caffine and aspartame if their retention factors were reduced by 28.0 %. Assume the mobile phase retention time (tm= 29.7 s) remains constant.
The half-life for the radioactive decay of U-238 is 4.5 billion years and is independent of initial concentration. How long will it take for 10% of the U-238 atoms in a sample of U-238 to decay?
Suppose that you have 175 mL of a buffer that is 0.300 M in both benzoic acid (C6H5COOH) and its conjugate base (C6H5COO%u2013). Calculate the maximum volume of 0.250 M HCl
An unknown compound contains only carbon, hydrogen, and oxygen(CxHyOz). Combustion of 5.50g of this compound produced 8.07g of carbon dioxide and 3.30g of water.
A buffer (pH 3.70) was prepared by mixing 1.00 mole of formic acid and 1.00 mole of sodium formate to form an aqueous solution with a total volume of 1.00 L.
Calculate how much heat is released when this reactions occurs at a constant temperature of 25.00 degree Celicus in a constant-volume container.
For each reaction, use the solubility rules as well the equations in the background information to predict if there is a reaction, If there is no reaction indicate so by writting NR under predictions, write gas for gas formation and PPT for precip..
Celsius is allowed to expand into an evacuated vessel of 2.50 L volume. Does the gas do work? Explain
Consider equal volumes (say 1 rm L) of a substance in the solid, liquid, and gas phases. Arrange them in order of decreasing mass. If the mass difference between samples is relatively small, rank the items as equivalent.
A 0.2 036 g sample containing only BaCl 2 and NaCl is dissolved in 5 0.0 mL of distilled water. Titration wi th 0.1410 M AgNO 3 requires 19.46 mL to reach the endpoint
A gas-filled balloon having a volume of 2.50L and 1.2 atm and 25 Celsius is allowed to rise to the stratosphere (about 30 km above the surface of Earth), where the temperature and pressure are -23 Celsius and 3.00 x 10^-3 atm, respectively. Calcul..
