Select the best answer that explains why a primary allylic radical is formed more easily than a primary radical whose neighboring carbon possesses an sp hybridization (i.e. a primary radical on a saturated hydrocarbon). a.) Primary allylic radicals are more easily formed in solution than primary radicals on saturated hydrocarbons because it is easier to solvate a primary allyic radical than a primary radical on a saturated hydrocarbon. b.) Primary allylic radicals are more easily formed because the vacancy in the half-filled p-orbital of the sp2 hybridized radical can be spread out over the p-orbitals in the neighboring pi-bond, whereas primary radicals on saturated hydrocarbons are limited to placing the radical on a single carbon atom. C.) A hydrocarbon with a pi-bond possesses more electrons than a saturated hydrocarbon. d.) A primary allylic radical is less sterically hindered than a primary radical on a saturated hydrocarbon, so it is easier to form a primary allylic radical. e.) A primary allylic radical is more pleasing to see than a primary radical on a saturated hydrocarbon
