WebLewis structures and the octet rule jointly offer a succinct indication of the type of bonding that occurs in molecules and show the pattern of single and multiple bonds between the atoms. There are many compounds, however, that do not conform to the octet rule. The most common exceptions to the octet rule are the so-called hypervalent compounds. WebCovalent bonds are more common than ionic bonds in the molecules of living organisms. For instance, covalent bonds are key to the structure of carbon-based organic molecules like our DNA and proteins. Covalent bonds are also found in smaller inorganic molecules, such as \text H_2\text O H2O, \text {CO}_2 CO2, and \text {O}_2 O2. planetary dictionary
