Concept explainers
(a)
Interpretation:
A molecule of octane has to be compared with one of a fat or oil and two differences has to be listed.
Concept introduction:
Fats are triglycerides made up of one glycerol molecule and three fatty acid molecules. They are also considered as the hydrophobic substances which are soluble in the organic solvents and insoluble in water.
Saturated fats are the one which contain saturated fatty acids in it and it cannot be hydrogenated.
Unsaturated fats are the one which contain unsaturated fatty acids in it and it can be hydrogenated further.
(b)
Interpretation:
A biodiesel molecule has to be compared with a fat or oil.
Concept introduction:
Fats are triglycerides made up of one glycerol molecule and three fatty acid molecules. They are also considered as the hydrophobic substances which are soluble in the organic solvents and insoluble in water.
Saturated fats are the one which contain saturated fatty acids in it and it cannot be hydrogenated.
Unsaturated fats are the one which contain unsaturated fatty acids in it and it can be hydrogenated further.
Biodiesel:
It can be otherwise said to be FAME(Fatty acid methyl ester) and is derived from the transesterification of triglycerides from biomass.
