Do ionic compounds have a low melting point
WebFeb 18, 2024 · The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. Ionic solids typically melt at high temperatures and boil at even higher temperatures. For example, sodium chloride melts at 801 °C and boils at 1413 °C. WebJun 20, 2015 · A low melting point also means that the inter -molecular forces that cause attractions between one molecule and another are not very strong. For example, a gas will have weaker intermolecular attractions than its liquid counterpart. Covalent Bonds. A covalent bond is formed when two atomic orbitals have optimal orbital overlap and …
