a. Demonstrate resonance structures of the electron donation of the NH2 group to the benzene ring in aniline. Properly utilize curved arrows and clearly indicate the + and - charges.
b. Define why the benzene ring is more reactive towards electrophilic aromatic substitutions and why the electrophile will predominately go to the ortho as well as para positions.
Many carbohydrate linkages are cleaved by hydrolytic enzymes, which is different from glycogen phosphorylase that uses phosphorolysis. There are two acceptable mechanisms for hydrolysis of the glycosidic bonds
The nitrate stock standard utilized in this experiment is 1000ppm NO3- prepared by dissolving 163mg of dried KNO3 in 100mL water. NaNO3 can also be utilized if no KNO3 is available. Explain what weight of NaNO3 must be used to make a 100mL solutio..
What is the mechanism of the formation of 1-bromobutane from 1-butanol using H2SO4 and NaBr? Also, how are1-butene and di-n-butyl ether are formed
Suppose 12.0 g of carbon (C) reacts with 65.0g of sulfur (S) to give 76.0 g of the compound carbon disulfide (CS2). In the process, all the carbon gets used up, but some elemental sulfur is left over. For the law of conservation of matter to b..
butanoic acid and 0.01 M NaCl. The ionization constant of butanoic acid is Ka = 1.52 × 10-5. Take the size of C3H7COO- to be 500 pm.
Suppose scheme one involves the reaction of the Grignard reagent containing more carbon atoms with the carbonyl compound containing less carbon atoms and scheme two involves the reaction of the Grignard reagent containing less carbon atoms with th..
the critical resolved shear stress for a metal is 25 mpa. determine the minimum possible yield strength in mpa for a
What is the correct order of decreasing heats of hydrogenation of the following Dienes. I. 3-Methyl-1,3-Hexadiene II. 3-Methyl-1,5-Hexadiene III. 4-Methyl-1,2-Hexadiene
A voltaic cell is constructed in which the cathode is a standard hydrogen electrode and the anode is a hydrogen electrode (P(H2)= 1atm) immersed in a solution of unknown [H+].
Write the structure of the compound that would result if the adduct were heated too long in the recrystallization solvent (CH3OH)
Calculate the concentrations of acetic acid and sodium acetate necessary to produce a pH 5.5 solution that is 0.5 M in total acetate concentration.
The A and B reaction has a rate constant of 5 x 10^-2 min^-1 at 25 degrees Celsius. Calculate the concentration of A in the 10th minute of the reaction if [A]0 = 0.15 M.
