Question
The dipole moment of the C-Cl bond is 1.67 and the dipole moment of the C-F bond is 1.65. This is best explained by: A. B. C. C-cl has a smaller charge separation than C-F due to electronegativity The C-F bond is more polar than the C-Cl bond Dipole moment is determined by charge separation and bond length -C-F has higher charge separation and C-Cl is a longer bond ole moment is determined by charge separation and bond length-C-f has higher charge separation and C-Cl is a shorter bond Either A or D offer the best explanation D. Dip E.Explanation / Answer
Halogens are more electronegative than carbonThis results in a carbon-halogen bond that is polarized. C as a partial positive charge, while the halogen has a partial negative charge.
As we progress down the periodic table from fluorine to iodine, size increases. As a result, we also see an increase in bond length. Conversely, as molecular size increases and we get longer bonds, the strength of those bonds decreases.
Thus C-F bond length is shortest and having the strogest bond and the C-I bond is the longest having the weakest bond. Also Of the four halogens, fluorine is the most electronegative and iodine the least. That means that the electron pair in the carbon-fluorine bond will be dragged most towards the halogen end.
Hence B is a suitable choice.
