Compare the bond strength of the indicated bonds (C-H) in the given compound :

structure

Answer:

Solution:

H₁ is on an sp² carbon (vinylic), H₃ is on an allylic carbon, and H₂ is on a primary alkyl carbon.

Stability of the radical : allylic (3) $>$ primary alkyl (2) $>$ vinylic (1). Bond strength is the reverse : 1 $>$ 2 $>$ 3.
