Question

What are the main differences between: alkanes, alkenes, saturated, and unsaturated fats?

Answer 1

The number of double carbon-carbon bonds in the molecule.

Explanation:

The main difference between alkanes and alkene is that alkanes have only single carbon-carbon bonds, while alkenes have at least one double carbon-carbon bond in them.

Saturated fats have all single bonds in then, while unsaturated fats contain double bonds. The bonds in a saturated fat are all single bonds because the double bonds have been reacted with hydrogen, `H_2`, which causes the double bonds to break open, and for hydrogen to attach onto the ends.
