Long Chain Fatty Acids has more carbon atoms. The carbon atoms are joined together, creating more bonds. Melt is the result of breaking these bonds. The longer the coal chains that higher the molecular weight of t6he fatty acids hence more energy coming from a higher Temperature.
And which fatty acid has the lowest melting point?
Unsaturated Fatty acids have lower melting points than saturated fat of the same length. For example the melting point of stearin acid is 69.6°C, while that of oleic acid (which contains a cis double bond) is 13.4°C. The melting points of polyunsaturated fatty acids of the C18 Series are even lower.
At what temperature does lauric acid freeze?
The freezing point of lauric acid is 44 degrees, based on the plateau observed at that temperature on the chart. 6. Freezing point depression: 44 degrees – 42ºC = 2ºC. exists neither as a liquid nor as a solid.
What is the melting point of stearic acid?
