Match the IR Spectrum
What structure would match the data ?
What molecule does this IR sprectrum show? Please explain how you got this answer. Thank You!
A student calibrated the mini-spectrophotometer with a blank solution, and then went to check their solution. They got a fingerprint on the cuvette while filling it. Because of this, the expected reading for the absorbance would be too high which would cause the calculated value of K, to be too high
1. 1H 19F has a force constant of 966 N m-1. Calculate the frequency of light corresponding to the lowest energy pure vibrational transition. The mass of 1H = 1.008 amu, the mass of 19F is 18.9984 amu, and 1 amu = 1.661 x 10-27 kg. 2. Draw Tryptophan in a peptide bond. Explain all of the bonds using valence bond theory (VBT). Next, explain where VBT fails and how molecular orbital theory is a better description of key regions of this amino acid and the peptide bonds it forms with other residues. 3. Below are the molecular orbital diagrams for B2, C2, and N2. Please use it to predict the bond order for B2, B2+ ,B2 -, C2, C2+, C2 -, N2, N2+, and N2-. Which of these molecules or ions would be paramagnetic? (The diagram has been attached) 4. What are the shapes of the molecular orbitals described in 3 above?
