A common by-product in this reaction is biphenyl, which is generated through a coupling reaction of phenylmagnesium bromide with unreacted bromobenzene. Draw the structure of biphenyl. Which part of your workup removed this by-product?
If nitrosyl bromide, NOBr, is 34 percent dissociated at 25°C and the total pressure is 0.25 atm, calculate Kp and Kc for the dissociation at this temperature.
Identify the element of Period 2 which has the following successive ionization energies, in kJ/mol. IE1: 1314, IE2: 3389, IE3: 5298, IE4: 7471, IE5: 10992, IE6: 13329, IE7: 71345, IE8: 84087.
Enough of a monoprotic acid is dissolved in water to produce a 0.0186 M solution. The pH of the resulting solution is 2.30. Calculate the Ka for the acid.
The volume the vapor occupies is 300 mL and the pressure of the vapor is 400 torr. The piston is then moved so that the vapor occupies 600 mL, and the system is allowed to come to equilibrium at 28 C. What is the final pressure of the CS2 in the v..
