Give the IUPAC names of the following compounds.

(a) CH₃CH₂C≡CCOOH

(b) CH₃CH(NH₂)CH(OH)COOH

Accepted Answer

Hey, everyone and welcome back. Give an appropriate systematic name for each of the structures shown below. Let's start with number one. And whenever we look at this compound, you may see that there's a code book Stochastic group over here, we can just label it. This is our car bookseller casted fragment because it's our C 00 H, right? And you may recall that according to functional group priorities, if you have an asset, that's the highest possible priority. So your compound for number one is an asset with respect to its parent, we understand that this is an asset and if it is an asset, carbon, number one will correspond to the carbon within the curb oxalic acid group itself. So our goal is to find the parent chain or based on the longest carbon carbon chain. And to do that, the only way for us to go is to go up and then to the left. So that's number one. Number two, number 34 and five, we have five carbon atoms. Now we have five carbon atoms and we wish to recall that five is 10. Okay. So that will be our prefects our suspects. For assets is awake. So we can say that we have pencil no weak acid overall. If we combine these two together, we will have our pencil quick acid. We always want to add that word asset to clearly say that yes, this compound is an asset. Instead of just adding a suffix, we're also adding a word asset afterwards. So we have pension OIC acid, but let's think if that's sufficient. We also want to incorporate any functional groups present in our compound. And you may notice how we have our triple bond between carbons three and four. Now, it's not an alkaline because this is not your highest priority. And whenever your triple bond acts as a substitution, that's how we can say it, right? We want to make sure that we're using iron as for our substitution. So instead of just having pencil like asset, we also want to say that at position number three, this is where our triple bond starts. We're going to say that we will have three iron, right? Position number three has a triple bond. Now, how do we combine these two together? Essentially, we want to say that if we start with our parent, right? Or basically our longest carbon chain, we are just going to say that we have and then we are going to say which carbon has a substitution. So we're going to say three, which substitution in which corresponds to a triple bond. And we are done with our substations. So we can just finish our name using our appropriate suffix and that'll be OIC acid. So the name for the first structure would be 10 3, I know Eric asset. Okay. So we are ready to move on to the second one. Once again, we clearly see that we have an asset over here. We have our code book silic acid fragment, which is the highest priority functional group. So we already understand that this will be our carbon number one, carbon, number 23 and four, that's our longest chain. So we understand that this is an acid, we have four carbon atoms. So that would be beauty. Okay. So this would be beauty and our suffix will be, oh I see. So that BB 10 OIC acid now it would be better economic asset if we didn't have any substitutions. But you can clearly see that if you go along your parent chain, position number three has two substitutions. Okay. So now at position number three, we have to substitute, wants one of them is an amino group, let's label it clearly in green. So this NH two substitution that's called an Amino group. And now additionally, we have our wage group right bonded at the same carbon atom. So that would be our hydroxy substitution even though you may think about this as an alcohol because it's our substitution, we already know that the main functional group is our asset. So a wage acts as an actual substitution instead of representing an alcohol. And whenever a wages a substitution, we call it hydroxy. So these two are seen at position three. So that's pretty much everything that we have to do. We just want to identify our substitutions. We will start naming our asset by adding appropriate substitutions and stating their positions. First of all, we will start with three because at position number three, we have our first substitution. And between the two, we have to think about the alphabetical order. Now amino group will go first because A comes earlier than age according to the alphabetical order, right? It gets the priority because in terms of an alphabetical order A starts first followed by age, right, according to the alphabet. Now, this means our first submission will be three amino because a guest priority over age alphabetically, Then we need to add our second substitution and identify its position. So first of all, let's add this positions so that B3 hydroxy, we are done with our substitutions and now we are ready to name our parents. So that would be beaten a weak acid. So that'd be the name for the second structure. We got our names. We can state that for number one, we got 10, 3, I know like acid. And for number two, we got three, I mean three hydroxy beats in OIC acid. These are our names. The correct answer to the multiple choice question is the thank you for watching.
