Vedclass · Answer

(B) The dipole moment $(\mu)$ depends on the electronegativity difference and the bond length. For methyl halides $(CH_3X)$,the order of dipole moment is $CH_3Cl > CH_3F > CH_3Br$. Although fluorine is more electronegative than chlorine,the $C-F$ bond length is significantly smaller than the $C-Cl$ bond length. This smaller bond length in $CH_3F$ reduces the dipole moment compared to $CH_3Cl$. Therefore,the correct decreasing order is $CH_3Cl > CH_3F > CH_3Br$.

Which of the following are arranged in the decreasing order of dipole moment?
