Question

Give two differences between Saturated and unsaturated fats.

Answer 1

No.	Saturated fats	Unsaturated fats
1.	In saturated fat, long chains of tetrahedral carbon atoms in the fatty acid get closely packed together.	In unsaturated fats, the presence of one or more C = C bond in long chains of fatty acids, prevent molecules from packing closely together.
2.	In saturated fats, the van der Waals forces between long saturated chains are strong. Hence, their melting points are higher than unsaturated fats.	In unsaturated fats, the van der Waals forces between long unsaturated chains are weak. Hence, their melting points are lower than saturated fats.
