please answer 1-4 &6
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...
