Question

pls answer with reason!!! ​

Answer 1

Answer:

Benzyl

Benzyl (C6H5−C∙H2) free radical is the most stable. The single electron on methylene C atom is in resonance with a benzene ring and is stabilized.

Answer 2

Both option 1 and 3 structures show Resonance.

structure 1 will also show hyper conjugation because it has 3 (alpha) hydrogen, but option 3 has only 1 (alpha) hydrogen.

But ........

Option (3) structure shows identical resonating structures.

Therefore it is more stable radical.

Let me know if there's any mistake.
