HOMEWORK CHAPTER 7 KEY 38. A carbon-oxygen double bond in a certain organic molecule absorbs radiation that has a frequency of 6.0 x 10 13 s -1 . a. What is the wavelength of this radiation? b. To what region of the spectrum does this radiation belong? c. What is the energy of this radiation per photon? Per mole of photons? d. A carbon-oxygen bond in a different molecule absorbs radiation with frequency equal to 5.4 x 10 13 s -1 . Is this radiation more or less energetic?
