Question

1 degree benzylic free radical is stable than 3 degree benzylic free radical?

Answer 1

Answer:

What can be said is that due to resonance, both the allylic and benzylic radicals are more stable than the t-butyl or ethyl radicals which are not resonance stabilized. ... Superficially, this might suggest that the benzylic radical is more stable than the allyl radical. This was the "answer" and reasoning provided here.
