Question
Find out the most stable species from the following. Justify
`dot"CH","CH"_3-dot"CH" - "CH"_3,` \[\begin{array}{cc}\ce{CH3 -\dot{C} - CH3}\\
|\phantom{.}\\\phantom{..}\ce{CH3}\end{array}\]

Solution
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.
