Same case here try arranging using carbocation stability...sp3 hybridised free radical is more stable than sp2..so I is least stable..now there is conjugation in II and III but in III we have tertiary radical so it is more stable..
IV is just a primary free radical
so the order is
I < IV < II < III
Arrange in order of stability giving reason.
Ans : I < IV< II < III
