Question
Which of the following are arranged in the decreasing order of dipole moment?
Options
A.CH3Cl, CH3Br, CH3F
B.CH3Cl, CH3F, CH3Br
C.CH3Br, CH3Cl, CH3F
D.CH3Br, CH3F, CH3Cl
Solution
Fluorine is most electronrgative and br is least electronegative. So CH3 F should have highest dipole moment but as C - F bond length is very small so inspire of greater polarity in CH3F, it has less dipole moment than CH3Cl.
