Bond dissociation enthalpy and bond enthalpy are not the same for

A

`O_(2) (g)`

B

`N_(2) (g)`

C

`CH_(4) (g)`

D

`F_(2) (g)`

Text Solution

Verified by Experts

The correct Answer is:
C
They are not the same for polyatomic molecules such as methane because in every dissociation step, bonds are broken is different species. Note that both bond dissociation enthalpy and bond enthalpy have the same symbols.
