What are covalent bonds? ionic bonds? A covalent bond can also be a double bond or a triple bond. A single bond is weaker than either a double bond or a triple bond. This difference in strength can be explained by examining the component bonds of which each of these types of covalent bonds consists (Moore Stanitski and Jurs 393). Usually a single bond is a sigma bond. A completely polar bond is more correctly called an ionic bond and occurs when the difference between electronegativities is large enough that one atom actually takes an electron from the other. The terms "polar" and "nonpolar" are usually applied to covalent bonds that is bonds where the polarity is not complete. To determine the polarity ... Conversely covalent bonds between unlike atoms often exhibit some charge separation and can be considered to have a partial ionic character. The circumstances under which a compound will have ionic or covalent character can typically be understood using Fajans' rules which use only charges and the sizes of each ion. An intermolecular force (IMF) (or secondary force) is the force that mediates interaction between molecules including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighboring particles e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. Carbides can be generally classified by the chemical bonds type as follows: (i) salt-like ( ionic ) (ii) covalent compounds (iii) interstitial compounds and (iv) "intermediate" transition metal carbides....
