Once 1-butyl-bisulfate is formed, the 1-butanol can act as a nucleophile to form dibutylether. Propose a mechanism for that reaction
ethanol or t-butyl alcohol were used instead of iospropyl alcohol in the attempted photochemical dimerization of benzophenone
What is the pH at the isoionic point? What is the pH at the isoelectric point? Explain the difference between your answers in (a) and (b), including specifically why one result is larger than the other.
The reaction of 2,2-dimethyl-1-propanol with HBr is very slow and gives 2-bromo-2-methyl-propane as the major product
Determine the quantity of stock 75% EtOH required to prepare 300ml of a 25% EtOH solution.
What is the heat change in J associated with 74 g of gaseous butane at 91 oC changing to solid at -170 oC? c(butane) (gas) = 2.31 J/ (g.K) c(butane) (liq) = 1.65 J/(g.K) c(butane) (s) = 1.32 J/ (g.K) ?Hfus(butane) = 6.885 kJ/mol
Since you need pressure based constant use ideal gas equation (PV=nRT) to convert moles of gas into pressure with units of atmospheres. R=0.0821 L atm/mol K
Estimate dissociation energy of HF using simpe additivity rule If given that d(H-H) and D(F-F) IN H 2 is 336kj/mol and F2 is 258 kj/mol
What is the boiling point of acetone at an elevation where the external pressure is 323 torr?
A bicycle tire is filled with air to a pressure of 720 torr at a temperature of 19 degrees Celsius. Riding the bike on asphalt on a hot day increases the temperature of the tire to 58 degrees Celsius.
A rigid flask is initially filled with 4.00 atm of NO2(g) and no N2O4(g) at 100 C. After equilibrium is achieved, the pressure of NO2 is 1.56 atm.
Determine the amount of heat (in kJ) given off when 1.89 104 g of ammonia are produced according to the following equation. Assume that the reaction takes place under standard-state conditions at 25.0°C.
What is the change in internal energy of the system, delta U. The force of gravity on a mass m is mg, where g is the constant acceleration of gravity (g=9.80 m/s^2).
