A hydrogen radical H• is known to abstract a hydrogen atom from an alkane in the same manner that halogen radicals do. Like halogen radicals, H• abstracts a hydrogen atom from a secondary carbon over a hydrogen atom from a primary carbon, in this case with a selectivity of 5:1.
(a) Draw the two isomeric propyl radicals that are formed on hydrogen abstraction from propane by H•
(b) Draw the curved arrow notation for the formation of each of these isomeric radicals
(c) Determine the percentage of each propyl radical that is formed, taking into account the different numbers of each type of hydrogen on propane
