How do you use molecular shape to predict molecular polarity?
How can you tell if there is a dipole moment or not?
A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.
Asked in Chemistry, Chemical Bonding
What is the difference between individual bond polarity and molecular polarity?
bond polarity is the polarity particular bond within a molecule, while molecular polarity is the polarity of the whole molecule. take for example water (H20): you could find the bond polarity of each H-0 bond (polar covalent), or the polarity of the whole molecule together (polar, because the electronegativity of oxygen is higher than the hydrogen atoms)
