How does NH2OH have a dipole-dipole intermolecular force? That means that NH2OH would have to be a polar molecule, but the electronegativity difference between all the elements is very small. Could someone please explain this? Maybe a picture showing the dipole moment if you could find one?
There is a dipole-dipole interaction on NH2OH because the electrons within the molecule are unequally shared. There is a nitrogen atom and oxygen atom that have higher electronegativities than hydrogen which means that the electrons would be pulled closer to these atoms. A good indicator if a molecule is polar or not in a tetrahedral shape is whether all the terminal atoms are of the same element; however, this molecule has a molecular shape of trigonal pyramidal due to only having three terminal atoms and 1 lone pair on the central atom.
