I’m sure you’ve heard the term “saturation” somewhere in the main stream media, probably in a commercial: “Tastes like butter but it’s 100% poly-unsaturated”.
What does it mean?
Saturation refers to the number of hydrogens relative the number of carbons. Alkanes are saturated (CxH2x+2) – all the carbons are either singly bonded to another carbon or to a hydrogen. Alkenes are “unsaturated” – there’s room for more hydrogens!
