Compare the bond dissociation energy of the labelled hydrogens (H_P, H_Q, H_R and H_S) in the following compound.
Options:
Answer:
C
Solution:
Bond dissociation energy is inversely proportional to the stability of the radical formed.
Stability of the radical : P (benzylic, resonance) R (secondary) Q (primary) S (aryl radical, orbital in the plane of the ring, no resonance).
So the bond dissociation energy order is S Q R P.
