Definition

Describing a substance that does not have distinct positive and negative ends, meaning it does not have a dipole moment and does not mix well with water.

Example

Oil is a nonpolar substance, which is why it does not mix with water.

Conversation

I learned that oil is nonpolar while water is polar.

That's interesting! So they don't mix well together, right?

Exactly! It makes sense why they separate in a bottle.

Yeah, chemistry can be pretty fascinating like that.

Synonyms & Antonyms

Root Explanation

Nonpolar → It is formed from "non-" (meaning not) and "polar" (from Latin "polaris", meaning of or pertaining to poles). The word "nonpolar" describes a substance that does not have distinct poles or charges, indicating a lack of polarity.

Memory Tip

Think of 'non-' meaning 'not' and 'polar' relating to 'poles' — so nonpolar means not having poles or charges.
