dipole moments

Postby Katherine Chhen 3I » Sun Nov 10, 2019 7:54 pm

Does the difference in electronegativity determine if a molecule has dipole moments?

Yes. The larger the difference in electronegativity, the larger the dipole moment.

Larger differences in electronegativity lead to larger dipole moments (the electrons are pulled towards the atom with higher electronegativity).

Yes, larger differences in electronegativity cause polar covalent bonding. However, certain molecular shapes, such as tetrahedral, tend to not have a dipole moment because the dipole moment is actually a vector sum between all polar bonds in the molecule.

Yes a greater difference in electronegativity typically results in a greater bond dipole moment.

Yes, the larger the difference in electronegativity the stronger the dipole moments of the molecule are.

Yes, electronegativity is how much an atom can attract electrons. A dipole moment is when one atom is strongly attracting the electrons more than the other. Thus, the dipole moment is centered from electronegativity.

If you visualize the electron cloud surrounding a molecule, it would make sense that the more electronegative atom(s) would pull the shared electrons closer to itself, forming a negative dipole moment on that region of the molecule and a positive dipole moment on the opposite end.
