उत्तर
The most stable species from the given species is `("H"_3"C")_3dot"C"` i.e., tert-butyl radical.
This is because it has a greater number of alkyl groups attached to the C-atom having an unpaired electron. More the number of the alkyl groups, the greater will be +I inductive (electron releasing) effect, and there by greater will be the stability of the free radical.
