Did you know?
WebSo the two molecules of hexane attract each other more than the two molecules of pentane. That increased attraction means it takes more energy for those molecules to pull apart … WebThe highest melting points are found in network covalent solids such as diamond, graphite and silicon dioxide. A giant covalent structure has many strong bonds holding it together. The next highest melting points are found in some metals, notably transitional metals.
WebThe melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid.At the melting point the solid and liquid phase exist in … WebAs a rule, larger molecules have higher boiling and melting points. Consider the boiling points of increasingly larger hydrocarbons. More carbons and hydrogens create a greater …
