Decision about dipole moment is present or not

How can you decide if there is a dipole moment or not?

A dipole moment is defined like an amount of the molecular polarity of a compound; magnitude of fractional charges on the ends of a molecule times the distance among them (in meters).
In direction for there to be a dipole moment, an element must have molecular polarity that results from molecules with a net imbalance of charge (frequently a result of differences in electro negativity). If a molecule has more than the two atoms, both bond polarity and shape determines the molecular polarity.
Overall, look for a difference in electro negativity of elements of a molecule that results in polarity and therefore a possible dipole moment. Reminde that molecular shape influence polarity so molecules with same elements but a different shape (and vice versa) will not have the similar dipole moment.
