Organic & Inorganic Compounds Online version Click on the physical and chemical properties that differentiate inorganic from organic compounds as they appear in the activity. by Leticia López 1 Organic compounds 2 Inorganic compounds React slowly, require catalysts Present the phenomena of isomerism The majority react irreversibly Bad conductors of electricity Most of these compounds are fuels Their boiling and melting points are relatively low Covalent bonds prevail (mainly non-polar) They represent almost 99% of the compounds in nature They are not soluble in water They represent about 1% of the compounds in nature Ionic and metallic bonds prevail Many of these compounds are soluble in water Their boiling and melting points are relatively high They are good conductors of electricity A lot of reactions with these type of compounds are reversible Very few of these compounds are fuels
