Determine the molecular formula and molecular mass of the compound represented by the chemical structure:

Mark the following on the spectrum scale and indicate the region of the spectrum (IR, UV, etc) in which each lies. For each, find a more precise value for frequency and wavelength in standard units than you can read from the plot. (1) Bond vibration corresponding to a wavelength: 6.5 um (find E in J) (2) Energy required to break a CH bond: 413 kl/mol (Find A in nm) (3) Energy required to remove an inner electron from a C atom: 308 eV (Find 2 in nm) (4) One of the rotational frequencies of a molecule: 12 GHz 12,000 MHz (2in cmJ (5) lonization energy of hydrogen atom: 13.6 ev (a in nm, E in kF/mol) (6) Frequency of a radio station: 91.7 MHz (Find 2 in m) (7)The energy of the n=4 to n=2 transition in H atom (Find A in nm)
