Molecular Compounds: The solid forms of molecular compounds are generally very soft and brittle. Covalent compounds are also more flammable than ionic compounds, due to the fact that they often contain Carbon and Hydrogen. Therefore, covalent compounds are softer, and more flexible. The fundamental principle of the science of chemistry is that the atoms of different elements can combine with one another to form chemical compounds. View editorial board . The reason for this fact, is that ionic compounds require a huge amount of energy to break their ionic bonds, and pull apart the positive and negative charges. Carbon dioxide cannot be considered an organic compound because it lacks hydrogen. 7.6 CiteScore.
