(a)
Interpretation:
The given set of triglycerides is fat or oil need to be identified.
Concept introduction:
Melting point of a compound is the temperature at which the compound starts to change from solid state to liquid state when temperature is raised. The total number of carbon atoms determines the melting point of the compound. Higher the carbon atoms and no unsaturation means higher is the melting point. If the melting point is low then the triglyceride will be in form of oil and if the melting point is high then the triglyceride will be fat. The generic structure of triglyceride can be drawn as,
To identify: the triglyceride containing one palmitic acid and two stearic acid residues as fat or oil.
