A sample of pure (1 chloroethyl) benzene had a specific rotation of 87.2 degrees, while pure R 1 chloro-1-phenyl ethane has a specific rotation of -109 degrees. This sample was reacted with excess ammonia in diethyl ether at 0 c. The product mixture had a specific rotation of -29.9 degrees. If the specific rotation of pure (R) 1-phenyl ethanamine is +39.3 degrees. This reaction resulted in [X] percent inversion and [Y] percent inverison, which idicates that the major mechanism was [Z].
What is [X]?What is [Y]?What is [Z]?
A buffer is made by mixing HCN and KCN to give a solution whose pH is 9.49. If the KCN molarity is 0.20 M, what is the molarity of the HCN?
Molybdenum crystallizes in a body-centered cubic lattice (the Mo atoms are at the lattice points only). If the density of the metal is 10.3 g/cm3, what is the unit cell edge length in pm?
Why was anhydrous, not wet, diethyl either used in the prepeatation and reaction of the Grignard reagent?
From the mean bond enthalpy data given below, estimate the enthalpy change for the complete combustion of one mole of butene at 298 K. (The molar enthalpy of vaporization of water is 45.0 kJ mol-1 at 298K)

an unknown compound has the formula CxHyOz. you burn .237g of the compound and isolate .347g of CO2 and .142g of H20. if the molar mass o te compound is 30.03g/mol, what is the molecular formula?
If units were explicitly specified for Kp of the reaction above, they would be [atm]n. What would be the value of n for this reaction?
Identify the cation and anion. Express the answer in terms of the formula of the salt. A green powder dissolves in water and gives a pure white precipitate with acidic AgNO3. When the solution is heated with H2O2 and NaOH, it turns a yellow color,..
