Water is a tasteless, odorless liquid at ambient temperature and pressure. With that, and the fact that cosθ=cos(−θ). The nonbonding pair on NH3 places a force on the bonds between nitrogen and hydrogen, forming a net dipole moment. Dipoles are vectors and just like in Physics, the geometry of the structure needs to be considered to determine if the forces cancel each other out. Consider a water molecule located at the origin whose dipole moment p points in the + x-direction. This is why boron trifluoride has no net dipole and hence no absorption in pure rotation. So a linear molecule like CO 2 has two polar bonds facing in opposite directions with the result that the molecule itself is not polar. Another question is to account for the big deviation for NH3, HF and H2O. nh4no3 + h2o = nh4oh + hno3 Dispersion is an intermolecular force that occurs in all bondings between elements. two poles that have opposite and equal electrical charge or magnetic force, with a space between….
