Simple molecular structure
What is Simple molecular structure?
A structure made of small, separate molecules. Inside each molecule the atoms are joined by strong covalent bonds, but the forces between one molecule and the next are weak. Melting and boiling only have to overcome those weak forces between molecules, so simple molecular substances have low melting and boiling points, and because the molecules carry no overall charge and have no delocalised electrons, they conduct electricity poorly.
