Dipole moments of molecules

See how individual bond dipoles add up (or cancel) to give the dipole moment of a molecule.

What to notice

Symmetric molecules such as CO₂, BF₃ and CH₄ have zero dipole moment; NH₃ has a larger dipole than NF₃ because the lone pair adds to the N–H dipoles.

Key relation

μ = q × d (debye, D) ; molecular μ = vector sum of bond dipoles

Why is the dipole of NF₃ so small?
