alkyl bromides and iodides color when exposed to light.explain?
Alkyl bromides and iodides when exposed to sunlight undergo homolytic fission of the C-X bond leading to formation of radicals.
These radicals them combine to form molecules of the halogens
R-X + hv --------> R. + X.
X. + X. -----------> X2
These molecules are dark in color.
