WebWe have already mentioned that the alkanes are relatively unreactive because of their stable C-C and C-H bonds. The boiling points and melting points of these molecules are determined by their molecular structure and their surface area. Some alkanes, from top left to bottom right: methane, ethane, propane, butane, hexane, octane and icosane. WebThe flammability of organic compounds is usually lower than that of inorganic compounds. The bond type of organic compounds is more often ionic than for inorganic The melting points of organic compounds are usually lower than those of inorganic compounds. The boiling points of organic compounds are usually lower than those of inorganic compounds.
