Answer:
The main difference between saturated and unsaturated fatty acids is that saturated fatty acids have no double bond and unsaturated fatty acids have one or more double bonds forming mon or poly-unsaturated fatty acid. An unsaturated fatty acid is usually liquid at room temperature
Step-by-step explanation:
Because of the presence of a double bond in the hydrocarbon chain of unsaturated fatty acid a bend is formed at that point. So, atoms are less tightly compact at that point. That is the reason it is in liquid form and more susceptible to reaction. while in saturated double bond all atoms are tightly packed in straight chain
