Solution

The correct option is A $C H_{3} C l > C H_{3} F > C H_{3} B r > C H_{3} I$
Dipole moment depends on the order of electronegativity of the central atom. The electronegativity order is F>Cl>Br>I but dipole moment in $C H_{3} F$ is less than $C H_{3} C l$ because bond length is shorter in $C H_{3} F$ . Thus, correct order is $C H_{3} C l > C H_{3} F > C H_{3} B r > C H_{3} I$

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
