Photochemical chlorination
Assume that all the methylene groups in the alkane are equally reactive as sites of free-radical chlorination.
a) Photochemical chlorination of heptane gave a mixture of monochlorides containing 15% 1-chloroheptane. What other monochlorides are present? Estimate the percentage of each of these additioanl C7H15Cl isomers in a monochloride fraction.
b) Photochemical chlorination of dodecane gave a monochloride fraction containing 19% 2-chlorododecane. Estimate the percentage of 1- chlorododecane present in that fraction.
