Question

Ultraviolet radiation, and radiation of shorter wavelengths, can damage biological molecules because it carries enough energy to break bonds within molecules. A typical carbon-carbon bond requires 5.78 x 1019 J to break. What is the longest wavelength of electromagnetic 8 pts. 17 radiation that can break a carbon-carbon bond?

Answer 1

From the given energy, wavelength could be found.

It is done in the attached figure:

- A typical carbon-carbon bond requires 5.7881019 to break. eie. the bond dissociation energy (E) is 5.78 810-19 g.. - longest 1. To get the wavelength we put the value of . 'E' and the constants 'h' and '' in the following formula: where, E Bond Dissociation Energy ca speed of light la wavelength of the radiation =) X = ne has Planck's constant = 6.626 X 10-34 A8 x 3x 188 m/s - 5.78 X 10-198 c) - 3.439x1014m - 343.9x109 m = 343.9 nm Therefore, the wavelength of electromagnetic radiation that can break a c-c bond is 343.9mm Longest
