Question: CH3Cl has more dipole moment than CH3F because :...
CH3Cl has more dipole moment than CH3F because :
A
Electron affinity of chlorine is greater than that of fluorine.
B
The charge separation is larger in CH3Cl compared to CH3F.
C
The repulsion between the bond pairs and non-bonded pairs of electrons is greater in CH3Cl than CH3F.
D
Chlorine has higher electronegativity than fluorine.
Answer
The charge separation is larger in CH3Cl compared to CH3F.
Explanation
Solution
Fluorine is more electronegative but dipole moment is the product of charge and distance between combining atoms (covalently bonded) ; due to more charge separation in CH3Cl, it has higher dipole moment.
