Concept explainers
(a)
Interpretation:
The skeletal structure for the given fatty acids needs to be determined.
Concept introduction:
In fatty acid, there is a straight chain of carbon atoms with attached hydrogen atoms. In the straight-chain, one end contains a carboxyl group(−COOH).
(b)
Interpretation:
The hydrophilic/hydrophobic portions of the fatty acids needs to be identified.
Concept introduction:
Usually, in fatty acid, there are 2 portions as head & chain. The hydrophilic part of any species is water-soluble and the hydrophobic part is water-insoluble.
(c)
Interpretation:
Depending on the skeletal structure, the fatty acid with a higher melting point needs to be determined.
Concept introduction:
The physical & chemical properties of fatty acids are markedly dependent on chain length and degree of saturation. If the length or size of the fatty acid is more, then it has a higher melting point. Also, the surface area of any substance and its bond strength is directly proportional to the melting point.
