The major resonance structure has one double bond. CHALLENGE: What are the formal charges here? Do you think a bent molecule has a dipole moment? Which direction does it point? Hint: Try drawing the resonance hybrid structure, and consider dipole moment vector diagrams like these when determining how to draw your dipole moment vector.

A flow dipole is a separation of a sink and a source. In a highly viscous medium, a two-beater kitchen mixer causes a dipole flow field. An acoustic dipole is the oscillating version of it. A simple example is a dipole speaker. Any scalar or other field may have a dipole moment. Dipoles can be characterized by their dipole moment, a vector ...

Dipole Moments. For each of the following, determine if the molecule would have a dipole moment (polar or nonpolar): 1. Draw the Lewis Dot Structure for each. 2. Determine the Electron Arrangement . 3. Draw the Molecular Geometry. 4. Find the electronegativities for each atom and draw an arrow along the bond toward the most electronegative element

Best Answer: You must look at electronegativity values, and also the shape of the ion or molecule. (NO2)- is bent, with a lone pair on the N. The O atoms are more electronegative than the N atom, so the N has a slight positive charge, and the O atoms share slightly more than a whole negative charge.

Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment.

NO2 (or nitrogen dioxide) is neutral as a gas, but can easily become NO2- (nitrite ion) in solution, demonstrating its polar nature. The polarity comes from the bent geometry of the molecule caused by the extra lone electron pair on the nitrogen.
