The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation Kp=Kc(RT)?n where R=0.08206 L?atm/(K?mol), T is the absolute temperature, and ?n is the change in the number of moles of gas (sum moles products...

3. Shown below are a series of reactions. Predict the major product for each of them. Remember, you will need to first decide whether the reaction occurs by an SN2, SN1, E2, or E1 before you can determine what the product will be. Label each as SN2, SN1, E2, or E1. Hint: First decide whether S2/E2 or S1/E1 is favored,...

6) There are a variety of isomeric 1,2,3,4,5,6-hexachlorocyclohexanes, but one of them does not react with CH CH,O to give an elimination product. Provide the structure of this compound and briefly explain why it does not react (5 points). When 4-chloro-2-methyl-2-pentene reacts with acetic acid (solvent), two substitution products are formed, with the rearranged...
