Is C8H18 an electrolyte or non-electrolyte
podryga [215]

C₈H₁₈ is a non-electrolyte

Why?

Electrolytes are substances that dissociate into ions when dissolved in water. In order to do that, they need to have bonds that are polar enough to be able to dissociate, and the ions formed need to be soluble in water.

C₈H₁₈ is a compound that has a low electronegativity difference between its atoms, making it to be a covalent compound where electrons are shared, and making it non-polar, and difficult to dissociate. Thus, it is a non-electrolyte.

One possible structure for C₈H₁₈ is attached below. It's called octane.

Have a nice day!
