CH5208: Applications of Molecular Spectroscopy
Question 1: Understand the underlying physical principles behind modern spectroscopic techniques;
Question 2: Describe qualitatively and quantitatively the information provided by 1D and 2D NMR, and UV-vis spectroscopies;
Question 3: Relate the appearance of UV-vis, 1D and 2D NMR spectra to the relevant structures and physical properties of molecular species;
Question 4: From an appreciation of molecular form and structure predict the appearance of UV-vis and NMR spectra for a wide variety of organic and inorganic molecules;
Question 5: Analyse and interpret spectroscopic data to deduce detailed information about the molecular structure and physical properties of inorganic and organic compounds;
when a sample of kcn of 6.00-grams is dissolved in h2o water in a calorimeter that has a total heat capacity of 2.156
A blank carried through the same procedure gave an absorbance of 0.045. If molar absorptivity of the Cu-containing colored compound is 7900, what is the amount of Cu in the rock sample (in mg)
H2O2 serves as an oxidizing agent or as a reducing agent. write equations for the reactions involved. what is the major difference between the conditions of the two reactions.
A 6.11g sample of a Cu-Zn alloy reacts with HCl acid to produce hydrogen gas. If the hydrogen gas has a volume of 1.26L at 22 degreesC and 728 mmHg, what is the percent of Zn in the alloy
Determine the empirical formula and the molecular formula of a compound that has the compostion of 80.0% C and 20.0% H. The molecular mass is 240.6 g.
Sulfurous acid, H2SO3, is a weak diprotic acid (pKa,1=1.89 and pKa2 =(7.21 at 25oC). What is the pH of 0.121 mol/L H2SO3(aq) at 25oC?
compare the stabilities of each of the four conjugate bases that would be formed from the doprotonation of the four different OH groups and determine which of hte OH is most acidic.
Why do you think the enthalpy of activation, (REFER TO THE PICTURE), for a syn-periplanar elimination is higher than that for an anti-periplanar elimination
How can you determine which substances would melt with such a flux? Take a hypothetical example. Suppose your table contained the mineral cuprite (a copper oxide) that has a melting temperature of 1235 °C
