Which one between C(6)H(5)CH(3)andCH(4) ...

Which one between `C_(6)H_(5)CH_(3)andCH_(4)` has lower `C_(sp^(3))-H` bond dissociation enthalpy and why?

Text Solution

Verified by Experts

Bond dissociation enthalpy of `C_(6)H_(5)CH_(2)-H` is less than that of `H_(3)C - H` as `C_(6)H_(5)overset(*)(C)H_(2)-H` is more stable (stabilised by resonance) than of `overset(*)(C)H_(3)` (which has no resonance stabilisation).
