Since you have posted multiple questions, we are entitled to answer the first only. 1) The stability of free radicals is directly proportional to the electron donating effect of the groups attached to it. Among the given radicals, the radical B is present in conjugation with double bond while the other radicals are not in conjugation with the double bonds. Hence the radical B will have resonance stabilisation while A and C will not. Hence the radical B is most stable. Now among A and C, the radical C is having more electron donating inductive effect as the carbon having radical is connected to 3 carbons while in A, the carbon is having less inductive effect as it is primary radical. Hence the radical C is more stable than radical A. Hence the order of stability of radicals are => A < C < B.
