Question

product for the reaction of limolenic acid with bromine, Br:. reaction 2. S 3. Show saponification reaction for the production of sodium palmitate from tripalmitin. 4. Three fats, labeled X, Y, and Z, were analyzed for double bond content and found to have "iodine numbers" of 78, 147, and 180. a) Which of the fats was the most saturated? b) Sketch a bar graph showing the results of the iodine number determinations for X, Y, and Z. 5. Use the Internet or print sources to determine some of the necessary precautions when working with bromine. How should you deal with a spill if one happens?

Explanation / Answer

Ans 2 :

Bromine reacts with unsaturated fatty acids , and adds to the carbon containing double bonds.

So there will be addition of two bromine atoms per double bond in the structure.

The reaction will be given as :

C19H34O2 + 2Br2 ---> C19H34Br4O2
