Academics

Dipole moments (mu) of CH3-Br and CH3-I are 1.81 and 1.62 D respectively. Explain what is the best explanation of the difference in dipole moments?

a) Dipole moments for all time decrease down a column of a periodic table.

b) Electronegativity differences are eclipsed by changes in bond length

c) Electronegativity differences outweigh changes in bond length

d) The dipole moments in CH3-I cancel out because of the very small difference in electronegativity between C and I
