Which has highest bond dissociation energy?

CH3F. CH3Cl . CH3Br. CH3I

PLS EXPLAIIN IN DETAIL ans is ch3F

MY opinion ch3I coz in ch3F F is more electronegativity so it has pulled electrons therefore it is easier to break the bond

And CH3I. I will nt attract electron compared to F

Solution

Due to the high electronegativity of the Halide ion (denoted by X-), there is a large electronegativity difference between C and X atom. Hence the C-X bond is not purely covalent and has significant polar character. Because the size of halide ion increases down the group, therefore the C-X bond length increases as we move down the group from Fluorine to Iodine. As bond length increases, bond strength decreases. The lower is the strength of a bond, the more is its reactivity as it is easier to break. Hence the relative order of reactivity for CH3Cl, CH3Br and CH3I will be

CH3I > CH3Br > CH3Cl

but CH3F is exception,CH3F have highest dissociation energy than other halide .
You have to remember this .it's only a exception.
