Using bond-line structures draw out the chemical reaction for the biodiesel synt

Question

Using bond-line structures draw out the chemical reaction for the biodiesel synthesis you prepared during last week's experiment (including the starting materials and the products). Assume that all of the fatty acid chains are linoleates (see Figures 1 and 2 in the introduction). You added 5 mL of 0.40 M NaOH in methanol to 20 mL of cooking oil. Calculate the number of moles of cooking oil, alcohol, and base that are initially present in the sample. Assume the density of the cooking oil is 0.895 g/mL and the molar mass is 885.43 g/mol. Look up the density and molar mass of any other compounds as needed. Assume your biodiesel synthesis reacts to 100% completion. What are the components of the biodiesel reaction mixture (after reaction time) based on the experimental stoichiometry (calculated in question 2 above)? Calculate the number of moles of each component. Predict which components will be soluble in water.

Explanation / Answer

3) a) methyl ester, glycerol and methanol present in the reaction mixture.

b) after solving problem 2) i got 0.02moles ( density =mass/volume, mass= 0.895*20=17.9grams and no of moles =17.9/885.4=0.02 moles) of oil,As per above equation one mole oil gives 3 moles of methyl acetate and one mole of glycerol.so 0.02 moles of oil gives 0.06 moles of methyl acetate and 0.02mole of glycerol.In this methanol was taken as excess quantity.

c) Methanol is soluble product and other are appear as two different oil layers
