Accepted Answer

Welcome back, everyone. Given the fatty acid or aic acid C 20 H 40 02 predict the shorthand notation which shows the number of carbon atoms and the double bonds determine if the, if the fatty acid is saturated or unsaturated mono or poly. For this specific problem, our shorthand notation would have a form of CX to Y, right. So essentially our goal is to determine numbers X and Y where X is the number of carbon atoms, CS, right? Let's call them carbon atoms. And why represents the number of double bonds. So for part number one, we want to use the formula for hydrogen deficiency index. It tells us how many rings or pi bonds we have in the structure. And according to the formula, we have to take one half multiplied by two, multiplied by the number of carbon atoms, then we have to add two and subtract the number of hydrogens. In this case, the number of carbon atoms is 20 and the number of hydrogens is 40. So first of all, we have to multiply two by 20 we got 40 we add two, that's essentially 42 right? And we also have to subtract 40. So 42 minus 40 this gives us two and two divided by two, gives us one. So the hygiene deficiency index is one and it basically means that we have a one pi bond in the structure because generally, we don't have any ranks and fatty acids. So it essentially means a one pi bond and one pi bond also means one double bond, right? So what is the notation? Well, essentially we are using CX to YX is the number of carbons and we have 20. So that'd be C 20. And now our Y value is the number of double bonds, which is one. So the notation would be C 22 1. That's the answer to the first part of the problem. For the second part, we want to determine if the fatty acid is saturated or unsaturated. If it has at least one double bond, we classify it as an unsaturated fatty acid. Mono means that there's only one double bond and poly means more than one multiple. So in this case, if we only have one double bond, it is mono unsaturated fatty acid and also be our answers. So the notation is C 22 1 and we can classify hierarchic acid as a mono unsaturated fatty acid. Thank you for watching.
