Decision about dipole moment is present or not
How can you decide if there is a dipole moment or not?
Expert
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.
The integrated forms of the first order rate equations are conveniently used to compare concentration time results with this rate equation. Rate equations show the dependence of the rate of the reaction on concentration can be integrated to give expressions fo
