Question

If central atom withdraws more electron it has more dipole moment

Answer 1

Because chlorine is more electronegative than carbon, chlorine pulls the bonded electrons closer to itself. The dipole moments 


In acetone, the resultant of the C-H bond dipole moments (although small) adds to the C=O dipole moment. B. The C-H bond dipole moments of acetone are greater in magnitude than C-Cl bond dipole moments of phosgene.
