Does a diamond have a high or low melting point? - Answers

WebFeb 22, 2014 · 97. 4. The melting point of graphite is slightly larger than the melting point of diamond, because in graphite C-C bonds have a partial double bond character and hence are stronger and more difficult to break. There are also Van der Waals forces between the layers of graphite but these are relatively weak in comparison to a covalent bond. WebRemember, diamond does not melt; it decomposes once enough energy is added to the system to break the C–C bonds. Under normal circumstances, the carbon atoms react with oxygen (O 2) in the air to form carbon dioxide - a process that requires the addition of lots of energy to reverse (as we will see later). rogan taliban in white houseWebHigh melting points and boiling points Ionic compounds have high melting and boiling points, so they are in the solid state at room temperature.
