How can a molecule with polar bonds be nonpolar?
If the shape is symmetric, the bond dipoles point in opposite directions and cancel, as in linear CO₂.
From the tool guide Ask a follow-upWhat is electronegativity?
How strongly an atom pulls shared electrons toward itself. The more electronegative atom gets the partial negative charge.
From the tool guide Ask a follow-upKey ideas
- A bond is polar when the two atoms differ in electronegativity.
- Bond dipoles are vectors: they can cancel out in a symmetric molecule like CO₂.
- A bent molecule such as H₂O does not cancel, so it is polar.
Things to try
- Load H₂O and CO₂ and compare.
- Make all electronegativities equal.
- Bend the bond angle.
- Find a polar molecule with a net dipole of zero.
Where this is used
Polarity explains why water dissolves salt, why oil and water do not mix, and how soaps and drugs work.
How to ask a question people can answer
A good thread on the Molecule Polarity Simulator saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
