False : The presence of polar bonds in a polyatomic molecule does not always lead to a definite dipole moment. This is because the dipole moment is a vector quantity and when the bond moment of one bond is cancelled by the equal but opposite bond moment due to other bond (s), the molecule has zero dipole moment, e.g. CO2, CH4, CCI4 etc.
