Problem- What differences in product distribution would be expected for the elimination reactions of 2-bromo-2-methylbutane and 2-bromo-2, 3-dimethylbutane with excess potassium hydroxide ethanol?
Please take care to answer each question mark in the equations
Draw the structure of dimethyl sulfoxide. Include any nonbonding electrons on sulfur, and minimize formal charges by allowing sulfur to expand its octet.
What is the change in internal energy of the system, with the system regarded as the CD player alone? Assume that the battery does 500 kJ of work on the CD player, which then does the same amount of work on the surroundings.
How much thermal energy is required to take a 42.0 g block of ice at -12 degrees C and heat it to steam at 131 degress C
Define why water spontaneously freezes to form ice below 0 even though the entropy of the water decreases during the state transition. Explain why is the freezing of water not spontaneous above 0
The ternary compounds called chlorofluorocarbons, or Freons, have proved to be very valuable as refrigerants and as cleaning agents for circuit boards. Unfortunately, in the atmosphere these compounds produce chlorine atoms that catalyze the decom..
