Triacylglycerol A contains 53% oleic acid, 29% linoleic acid, 9% palmitic acid, 4% stearic acid, 1% myristic acid and lesser amounts of other fatty acids. Triacylglycerol B contains 39% oleic acid, 29% palmitic acid, 24% stearic acid, 2% myristic acid, 2% linoleic acid, and lesser amounts of other fatty acids. Which of the two samples is expected to be solid at room temperature? Why pls? Thanks

Trimyristin is a fatty acid ester of myristic acid and glycerol. Draw the structure of the products of the base-catalyzed hydrolysis of trimyristin. Using this reaction, calculate a theoretical yield if you started with 1 g of trimyristin. Upload a picture showing all of your calculations. In our experiment we used 50mL of DCM and then refluxed and preformed a distillation to removed the excess DCM. We then used cool acetone to wash the crystals and then did vacuum filtration.

A) B) only. B) A) and B) are both correct C) A) only. D) C) only.
