Question

question 34 of 60octane, $ce{c8h18}$, spreads out on waxed paper. do you expect octane to dissolve in water? why or why not?○ yes, octane will dissolve in water because octane is polar, and water is also polar.○ no, octane will not dissolve in water because octane is polar, and water is also polar.○ no, octane will not dissolve in water because octane is nonpolar, and water is polar.○ yes, octane will dissolve in water because octane is nonpolar, and water is polar.

Explanation:

The solubility rule "like dissolves like" applies here. Polar substances dissolve in polar solvents, while nonpolar substances dissolve in nonpolar solvents. Octane ($C_8H_{18}$) is a hydrocarbon, which is nonpolar. Water is a polar molecule. So octane will not dissolve in water.

Answer:

No, octane will not dissolve in water because octane is nonpolar, and water is polar.
