A carbon=carbon bond is a characteristic of alkenes and is two pairs of electrons bonding two carbon atoms together.
Saturated. This is because with no carbon-carbon double bonds the bonding sites are taken up by hydrogen, thus saturated. These saturated fats are solider tha unsaturated fats containing...
similarity: both have bonds involving four shared electrons. differences: c=o is polar; c=c is not polar.
