Ionic and metallic bonds prevail
Their boiling and melting points are relatively high
They are not soluble in water
Bad conductors of electricity
They represent about 1% of the compounds in nature
Present the phenomena of isomerism
They represent almost 99% of the compounds in nature
Most of these compounds are fuels
They are good conductors of electricity
Many of these compounds are soluble in water
Very few of these compounds are fuels
React slowly, require catalysts
A lot of reactions with these type of compounds are reversible
Covalent bonds prevail (mainly non-polar)
The majority react irreversibly
Their boiling and melting points are relatively low
