Question

For each of the following, give the systematic name and the common name (if it has one) and then indicate whether it is a primary, secondary, or tertiary amine:

c. Structural formula of an amine with a nitrogen atom bonded to three carbon chains, indicating its classification.

Accepted Answer

Welcome back, everyone determine the systematic and common names for the molecule given below and specify if it is primary secondary or tertiary. Now, what we immediately noticed is that there's nitrogen with two alky groups bonnet set and that nitrogen atom also has hydrogen bond set. So whenever we start with ammonia and we replace 12 or three hygiene atoms with alky groups, we get an amine because we have two alky groups, one, it's nitrogen on the left and on the right, we can classify it as a secondary, I mean, right, because the number of alky groups bond its nitrogen defines the degree of that amine. And in this case, we have a secondary amine. Now, whenever we have a secondary amine, we can simply define a common name very easily. In general, the common name will have a form of alki I'll kill. I mean, this might look confusing, but this is definitely a good rule. If we have a secondary amine, we are simply going to state the two alkyl groups that are bonded to nitrogen and finish our name with amine. And of course, we want to define those alki groups as well. As arrange them alphabetically. So on the left, we have 123 carbon atoms. That's a propal group because it's a straight chain on the right. We have a secondary beetle group. So we are going to say sac beetle, right? Because we have 1234 carbon atoms and we're bonding our beetle group to the nitrogen atom, add carbo number two. If we want to arrange them alphabetically, we're going to start with S A beetle, we are going to ignore S A and we're only going to focus on B, right. So B versus P gets priority and then the prop group will be the next group in our name. So the first one will be Sag Beatle. That's our first alki group because we are arranging them alphabetically. Then the second alky group is propol. So we're going to say S beetle, I mean, and that's our common name. Now, let's think about the systematic name. When it comes to systematic names, it might be a bit more difficult, but no worries, we'll go, we're going to break it down. What we want to do is focus on the rules that we use whenever we name alkenes. So let's consider the two alki groups, bonds nitrogen. And let's find the longest continuous carbon chain on the left, we have we carbon atoms within the prop group. So that's our longest continuous carbon chain on the right, we will have 1234 carbon atom in the longest continuous chain, meaning we are going to choose the four member chain as our parent. So let's erase everything to clearly see what we're trying to perform. Now, we already understand that our parent will be our Sex Beatle group if we want to define it that way. But actually we are going to look at butane, right? And specifically number one, our parent will be Butane but because we're actually dealing with an a mean and not an al can we are going to get rid of that e at the end and replace it with a mean, everything would be great. But we also want to clearly specify where the amino group is for that purpose. Let's enumerate our parent, we can enumerate it two ways going down and then the right or reversing our path. And between the two paths, we will choose the one that minimizes the low current for the nitrogen atom. So that would be our blue pathway. And this means Butan amine becomes bean C I mean, which clearly states that the nitrogen atom is bonded to carbon. Number two, well done. Now butane itself doesn't have any substitutions, but the nitrogen atom bonded to carbon number two has a propal substi, right? And because that propal substituent has bonded NGEN, we're going to say that nitrogen has a propal substi and to define it based on the I pack rules, we are going to say M dash propel which clearly allows us to understand that the propal group is bonded in the and that's it. We can just combine these together and we can say that the systematic name would be an and then that's it. But we simply want to finish the name with the parent beat San two, I mean, great job. So let's conclude our findings starting with the common name. We said that would be Alki Al Kill, I mean, and we arranged them alphabetically. We got Sack Bile Bill. I mean, now for the systematic name, we primarily used our came naming the rules. We said that there was B sane in the longest continuous carbon chain. We got B 10 2 amine and we added our substituent which is the and finally, the classification would be a secondary. I mean, that's because there are two alky groups bond at in. Let's go ahead and label our final answers. Thank you for watching. And I hope to see you in the next video.
