Ultraviolet radiation and radiation of shorter wavelengths can damage biological molecules because they carry enough energy to break bonds within the molecules. a typical carbon–carbon bond requires 348 kj/mol to break. what is the longest wavelength of radiation with enough energy to break carbon–carbon bonds?

343.98 nm is the longest wavelength of radiation with enough energy to break carbon–carbon bonds.

Explanation:

A typical carbon–carbon bond requires 348 kJ/mol=348000 J/mol

Energy required to breakl sigle C-C bond:E

where,

E = energy of photon

h = Planck's constant =

c = speed of light =

= wavelength of the radiation

Now put all the given values in the above formula, we get the energy of the photons.

343.98 nm is the longest wavelength of radiation with enough energy to break carbon–carbon bonds.
