Accepted Answer

Welcome back every once in another video, provide the I pack and common names if any for each structure shown below. First of all, let's notice that all of these three structures are carboxylate souls. So let's begin solving the problem. Now, if these are carboxylate salts, we first of all have to recall that our names, both are you p and common names will begin with the metal carion involved. So now for a, the metal cion is the potassium cion. So we're going to state potassium if we move to B, the cion is sodium. Now for C the carry on is potassium once again, because we can see the charges, right. So we can once again, state potassium from here, we can essentially begin writing the complete name for each structure. What we want to understand is that since these are carboxylate souls, they always end with O A ce. Oh Wait. Right. So what we want to do is essentially count the number of carbon atoms in the longest continuous chain starting with Carboni. For the first one, we only have one carbon. And we know that an alkane with one carbon is methane. So in this case, we can just state that the name would be Methano weight, we're taking methane, we're dropping that E right? And then we combine it with O A ce and essentially, it means that we have methane a weight within our name. So that would be the IAC name. And we can continue with B in a very similar way. If we identify the number of carbon atoms in the longest continuous chain, we have a total of three carbons. So that would be pro Panno, we're going to stay pro panel. But the main issue is that the structure is a bit more complex. There's a methyl substi bonded to carbon. Number two, let's recall that carbon number one is always the carbon atom within carbona. So we simply want to state that it is two methyl Proano because there is that additional methyl substituent within the parents. So the Iupac name would be sodium two methyl Proano. And now what about C? Well, for C our parent is a bit more complex. Notice that bonded to carbona, we have a benzene ring. So overall, whenever benzene is bonded to carbona, we call it benzoate. Almost same rules, right? Oat at the end, we take benzene and it becomes benzoate. However, we have a small issue because there's a bromo substituent bonded to the benzene ring. So if we enumerate our benzene ring, starting with position number one being bonded to carbona, we can see that we have 12, we and four, right, the bromo group is bonded to carbon. Number four, we went to minimize the low count. Whether we go clockwise or counterclockwise. It doesn't matter. It's always position number four. So that would be potassium or bromo benzoate for the Iupac name. Now, let's focus on the common names. Now, what we want to understand is that common names, they typically allow us to change the parent into some common name but nothing else changes. So we are going to begin with the cat, I am. So we have potassium, but instead of methano weight, we're going to choose a common representation of methano weight, which is formed, right? We can say methano acid or formic acid. And this is also applicable to carboxylate. We can say methano or, or are made. Now, if we look at B, we once identified the common name for the alk substituent Bnei Carba. Now, if we consider all of those carbons, we have a total of four carbons in the parent, right? And essentially whenever we have branching at position number two, this is called an Isobel substituent. So what we want to do is simply begin with the same method. And now instead of stating two methyl Proano, we're going to state iso be the rate which represents a, we remember chain with branching at position number two with a metal substituent. And finally, for C, well, the common name is not applicable because the substituent is too complex. We have a six member grain instead of a standard Lky substituent and those would be the final answers to this problem. Thank you for watching.
