And in the second beaker, we have a fatty acid that contains this CIS double bond. What exactly is the difference between one beaker and the a second beaker? Well, in the case of no double bonds, so this molecule, minus this double bond, the molecule will essentially be a linear straight chain molecule. And that means they can stack on top of one another very well. And by stacking very well, we have a very small distance between the molecules. And if the distance is smaller, the intermolecular bonds are stronger.
