is gasoline made up of ionic, polar, or non-polar molecules?

Answer 1

Barswhere and Dave Star are right. Mostly. The short answer is "non-polar". The more complete answer is "mostly non-polar, some polar, no ionic"

Aromatic (ring structures like benzene), straight chains (like octane) and branched (like dimethyl hexane) are made of only C and H and are all non-polar.

There are polar compounds in gasoline but as more minor fractions. All detergents, which all gasolines contain, have a polar end and a non-polar end.

"Oxygenated" compounds are mandated in some jurisdictions (usually due to high winter ozone levels). It can be methanol, ethanol, mTBE, etc in fractions from 5 to 15%. That oxygenated group (C-O-O-H, etc) makes the compound polar.

Ionic? Nope, none. That's stuff like NaCl that disassocates into Na+ and Cl- in water.

Answer 2

Is Gasoline Polar

Answer 3

Non-polar. The components of gasoline are a specific fraction of the hydrocarbons from crude oil. Hydrocarbons are all non-polar. Organic molecules don't become polar until you add atoms like oxygen, nitrogen, halogens, etc.

Answer 4

non-polar. most of the bonds are c-c or c-h, which are non polar
