Question

An ether extraction of nutmeg gives large quantities of trimyristin, a waxy crystalline solid of melting point 57 °C. The IR spectrum of trimyristin shows a very strong absorption at 1733 cm-1. Basic hydrolysis of trimyristin gives 1 equivalent of glycerol and 3 equivalents of myristic acid (tetradecanoic acid).

(a) Draw the structure of trimyristin.
(b) Predict the products formed when trimyristin is treated with lithium aluminum hydride, followed by aqueous hydrolysis of the aluminum salts.

Accepted Answer

Hey everyone. Let's do this problem. It says extraction of peanuts gives trio leon in good quantities. It's Ir spectrum shows a strong peak at 17 22. It is a liquid with a melting point of five degrees Celsius when it is hydrolyzed in a basic medium, one equivalent of glycerol and three equivalents of a lake acid are obtained one or a draw. The structures of trillion B show the structures of its products when treated with lithium aluminum hydride followed by acquis hydraulic sis. While to get the structure of trillion, we should condense the products which were obtained by its hydraulic sis which were one equivalent of glycerol and three equivalents of Oleic acid. So we'll draw the glycerol Which is CH 20 h CH h CH 20 H. And three equivalents of Oleic acid, C H three CH 27 C H double bonded to C H ch 27. And we have a car box silic acid functional group. And these will give our trillion, which is basically like our glycerol. But we've replaced the alcohol group with an ester group by connecting basically the Oleic acid to the glycerol. So we have C H two O C double bond, oh CH 27 carbon carbon double bond CH 27 ch three. And it's three of these all connected just like in the glycerol, our ester group seven Ch 2 groups, our double bond seven More CH two groups in our methyl group and one more. Okay so that is part one our structure of trillion. So now let's copy that because in part two we want to show the structure of its products when treated with lithium aluminum hydride, followed by Aquarius hydraulic sis. So now we're starting with our trillion pieced oops. And we're treating with lithium aluminum hydride, LIALH four And H 30 plus. And this is going to reduce the ester bond into alcohols, which will give one equivalent of glycerol and three equivalents of Oleic acid. So it's basically the opposite of what we just did. I'm going to piece these products as well or copy and paste. All right. And all this gives a to be the correct answer for this problem. That's it for this one.
