Vedclass · Answer

(B) Hyperconjugation in free radicals requires the presence of $\alpha$-hydrogen atoms (hydrogens attached to the carbon atom adjacent to the radical center).$1.$ In option $(a)$,$CH_3-C(CH_3)_2-C^\bullet H_2$,the carbon adjacent to the radical center is a quaternary carbon with no hydrogens ($0$ $\alpha$-$H$).$2.$ In option $(b)$,$CH_3-C^\bullet(CH_3)-CH_3$,there are three methyl groups attached to the radical center,providing a total of $9$ $\alpha$-hydrogens. Thus,it shows hyperconjugation.$3.$ In option $(c)$,$CH_2=CH-C^\bullet H_2$ (allyl radical) is stabilized primarily by resonance.$4.$ In option $(d)$,the benzyl radical is stabilized primarily by resonance with the benzene ring.
