3. [5] Retinal consists of a chain of carbon atoms roughly 1.5 nm long. Electrons in...
The retinal molecule has 12 electrons that are free to move about the chain. For reasons that you may learn later, these 12 electons fill the first 6 states of the box (with 2 electrons in each state). (Figure 1) Thus, the lowest energy photon that can be absorbed by this molecule would be the one that moves an electron from the 6th state to the 7th. Use the equation that you found in Part A to determine the wavelength...
1.33 Electrons in molecules are described by wavefunctions that extend over more than one atom. Consider an electron that is described by a wavefunction that extends over two adjacent carbon atoms. The electron can move freely between the two atoms. The internuclear C-C distance is 139 pm. (a) Using the one-dimensional particle-in-the-box model, calculate the energy required to promote an electron from the n=1 to the n = 2 level, assuming that the length of the box is the same...
1) Write a Reaction equation using 4- aminobenzenesulfulfonic acid (aniline derivative) and 8-anilino-1-naphthalenesulfonic acid (coupling agent). Write the mechanism. SYNTHESIS OF AZO DYES INTRODUCTION Humans' love of color dates back almost to prehistoric times, yet it is not actually until the modern era that the full range of the rainbow has been accessible to the majority of people irn their clothes and other textiles. Ancient or medieval times have often been described as being quite splendid with their "tyrian purple"...
