Questions The energy of UV light is 70 kcal/mole at 400 nm and 140 kcal/mole at 200 nm. Why is UV radiation damaging to the eyes and skin? (Hint: Think about the energy required to break a C-C bond.) 2. Which is more energetic: 235 nm or 325 nm light? Explain. 3.) Why is UV spectroscopy used more frequently in organic chemistry than visible spectroscopy? 4. Using the structure of methyl orange as an example, draw...
4. Draw the Lewis Structure for the following compounds or ions. Determine the sun molecule/ion. State whether the molecule/ion is polar or nonpolar. If appropriate, draw the net dipole moment; an arrow indicating the direction of the dipole moment molecule/ion (you will need to think about which bonds are polar to do this). a.
