Question

F2 has lower bond dissociation enthalpy than cl2 why

Answer 1

Answer:

BCz bond length of fluorine is smaller than cl

Answer 2

Answer:

since size of fluorine is small so there is a large interelectronic repulsion between fluorine atoms than chlorine and chlorine is large enough to compensate the interelectronic repulsion and hence is more stable and high bond dissociation enthalpy
