Compare the bond strength of the indicated bonds (C-H) in the given compound :
Options:
Answer:
A
Solution:
H₁ is an aryl hydrogen (sp², strongest bond), H₂ is benzylic (weakest bond because the benzyl radical is resonance stabilised) and H₃ is on a secondary carbon.
Radical stability : 2 3 1, so bond strength is 1 3 2.
