One of the first thionitrosyl complexes to be synthesized and studied was (Cp)Cr(CO)2(NS) (8 points)
This complex has CO stretching bands in the infrared at 1962 and 2033 cm-1. When the NS is replaced with the isoelectronic NO to form (Cp)Cr(CO)2(NO) the CO stretching vibrations shift to 1955 and 2028 cm-1. Based on this information is NO or NS a weaker π acid?
Upon UV irradiation one CO ligand is lost to form (Cp)Cr(CO)(NS) as a reactive intermediate. Draw the product you would expect from the reaction of this intermediate with H2 and describe the orbital between the metal and H2 needed to form that product.
Calculate the density of propanol C3H8O if you know that there are 1.069×10 25 molecules of propanol in 1.35 L.
(i) Propose two resonance forms (that respect the octet rule and energetically nonequivalent) contributing to the structures for each of the following molecule and ion.
1-ethylcyclohexene + diborane in diglyme go after by an aqueous solution of sodium hydroxide and hydrogen peroxide.
What is the reaction order with respect to NO2. If the initial concentration of NO2 is 0.200 M, what is the concentration of NO2 after 10 minutes
One has a dipole of 0 D, and the other has a dipole moment of 2.95 D. Draw the structure of the stereoisomer with dipole moment of 2.95 D.
Calculate the Ksp for Na2B4O5(OH)4 from this data. d. What is the free energy change for the dissolution of Na2B4O5(OH)4 at this temperature?
Draw the major product for each of the following reactions. Make sure that you draw a major product that could be isolated, not just an intermediate or something that would be present only in low equilibrium population.
find the molar mass of the unknown. 16.6 degrees C freezing point acetic acid and 3.90 degrees C*kg/mol?
55.0 mL of a 1.70 M solution is diluted to a volume of 278 mL. A 139 mL portion of that solution is diluted using 175 mL of water. What is the final concentration
what is the change in enthalpy when 18.4 g of steam at 100?c is converted to liquid waterat the same temperature and
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 11.9 torr at 35°C. The vapor pressure of pure ethanol at 35°C is 1.00 multiplied by 102 torr
Problem- Calculate the pH at the equivalence point for the titration of 0.170 M methylamine (CH3NH2) with 0.170 M HCl. The k_b of methylamine is 5.0*10^-4.
