Draw the structure of an organic compound: a. that has the formula C7H12O and has peaks at 2950 cm-1, 2750 cm-1, and 1745 cm-1 in it's IR spectrum. b. has the formula C6H10 and a UV absorption with lamba max = 235 nm. c. has the formula c6H12 and yields a single monochlorination product on irradiation with UV light in the presence of Cl2. d. has the formula C6H4Br2 and gives rise to a single 1H NMR signal.
If the process occurs adiabatically and at constant (atmospheric) pressure (a) what is the mass of water that solidifies and (b) what is the change in entropy of the system?
At 700 K the equilibrium constant for the reaction is Kp = 0.76. CCl4(g)-> C(s) + 2 Cl2(g) A flask is charged with 2.00 atm of CCl4, which then reaches equilibrium at 700 K. (a) What fraction of the CCl4 is converted into C and Cl2?
