Web1) Oil has a density less than water, so it just sits there on the top, not spreading out into the more dense water below. 2) Oil is very nonpolar, meaning that a polar molecule like water doesn't get attracted to it. Oil is … WebIonic compounds tend to have higher melting and boiling points, covalent compounds have lower melting & boiling points Ionic compounds tend to have more polar molecules, covalent compounds less so Organic compounds tend to have covalent bonds Ionic compounds are usually between a metal and a non-metal.
