Vedclass · Answer

(B) The bond enthalpy of the $C-X$ bond depends on the bond length. As the size of the halogen atom increases from $F$ to $I$,the $C-X$ bond length increases.According to the inverse relationship between bond length and bond strength,as the bond length increases,the bond strength decreases.Since $F$ is the smallest halogen,the $C-F$ bond is the shortest and strongest,requiring the highest energy to break.Therefore,$CH_3-F$ has the highest bond enthalpy among the given alkyl halides.
