Describe any new ways you can change the polarity of the three-atom molecule.

- By changing three atom bond angle, we can change molecular polarity. if bond angle is 120° and all atom has same electronegativity, the resultant polarity (dipole moment) become zero. we can change bond anngle either less than or greater than 120°, but not exactly 120

- Replacing one or more atom with different atoms having electro negativity values also make molecular poles.

- By placing molecules under external electric field or magnetic field also causes to the molecule.
