The Nitrosyl fluoride structure data file can be imported to most of the cheminformatics software systems and applications. Although the magnitude of the bond moment will not change based on whether B is the most electronegative or the least, the direction of the bond moment will. 2023 ChemEssen, Inc. All rights reserved. (b) In H2O, the OH bond dipoles are also equal in magnitude, but they are oriented at 104.5 to each other. (b) The electronegativity difference between B and F is much larger, so the vector representing the dipole moment is much longer. This charge polarization allows H2O to hydrogen-bond to other polarized or charged species, including other water molecules.
