Welcome back everyone. A mixed Tr Ayl Glycerol consists of the following components, two mistic acid molecules and one auric acid molecule on the center carbon of Glycerol draw its condensed structural formula. What we want to do is simply begin by drawing the structure of Glycerol. We know that Glycerol has a three member chain. Those three carbon atoms are bonded to hydroxy groups, right? And each carbon must have four bonds. So we need to add an appropriate number of hydrogens 21 and two respectively. Whenever we are forming a Tr Ayl Glycerol, we want to remove those hydrogens and replace them with carboys and those Carbonis, they are part of each carboxylic acid. So let's add carbonyl co and our goal is to simply determine the side chain bonded to carbona. As the problem suggests, there are tumeric acid molecules C 14 0 and they are bonded to carbons one and three because Laic acid is on the center carbon, right. So our C 12 0 is bonded to C two or basically it is bonded to carbel or is part of carbonel bonded to oxygen that is bonded to position number two, that would be more accurate to say, right. So let's understand this notation. Now, c 14 0 means that we have war carbons, zero double bonds. And we are assuming a straight chain, basically a linear chain. So essentially we want to understand that those are bonded to positions one and three. So we want to add a set of C two units because this is what we have in a straight chain followed by the terminal muscle group. We simply want to determine how many seeds to units we have. So if we already see 12 carbon atoms, we have to subtract two from 14. And this leaves us with 12 repeating CH two units. And as we can see, we have the same size chain for position number three, right? So CH 2, 12 times CH three and then we have Loic acid at position number two, it essentially has 12 carbons, zero, double ones. Similarly to what we did before we have to take 12 minus two to get 10 CH two units followed by the terminal methyl group. And we have drawn the required tr ayl glycerol for this problem. Thank you for watching.
