Name the following compounds: c. (CH 3 CH 2 CH 2 CH 2 ) 2 NH 2

Hi, everyone. Welcome back. Our next question says, provide the name of the given compound we have in parentheses ch three ch two, CH two, CH two, CH two, CH two and then subscript two NH. And our answer choices are A N hexamine, B 11 die Hexane. I mean see diolamine, DN diolamine. So let's think about this compound and the naming rules for it, we haven't, it isn't a meme and it has two R groups, these two hydrocarbon chains and it's important to know that they are identical. So because we're naming a means whether those branches are identical or different is important in how you name them. So let's think about this naming rule. So when naming a means we know we have a secondary amine. So that's two with a little degree sign since our nitrogen has two carbons bounded to it and it is symmetrical. So when you name a symmetrical secondary, I mean you use a prefix in this case die since we have two of these symmetrical groups, and then we use the alcal name as a branch plus the word A mean if we had for instance, a primary amine we would simply name this as al el amine. Then with, as we said, a symmetrical secondary amine or a symmetrical tertiary amine, we would use that prefix either die for secondary or try for tertiary. The alkyl name in the amine, if we have a secondary or tertiary, I mean that is not symmetrical. So the branches are not the same, you name it as an N substituted, I mean where the longest chain carbon is your primary, I mean, and then you would name the chain as N something showing it's attached to the nitrogen. So it won't have a number because your branch is not attached to a carbon. It has an N, but you only need to do that when it's not symmetrical. In this case, you have two of the same branch. So since we use our prefix, we should have a prefix dye and then we have the alkyl name. So we need to count how many carbons we have. So we have 123456 carbons and we name it as an alkyl. So we'd have di heel and then a mean. So we see that that is answer choice. C when we look at our other answer choices, choice A N Hexane amine, we wouldn't use that. We only use the N if we have an unsymmetrical secondary or tertiary amine. And then you would have two names because you, by definition two or three names, you would have the primary, I mean, and then the N used to designate your other shorter chains. So that's why choice A is incorrect. Choice B 11 di hexane amine doesn't make sense because the 11 would refer to a carbon atom in the unsymmetrical means you use N to show the placement of your chain. So choice B is not the correct nomenclature. And then choice DN diolamine, you don't need the N because these are symmetrical. So choice D is incorrect. So once again, the correct name for this compound is choice C diolamine. See you in the next video.

Textbook Question

Name the following compounds:
c. (CH₃CH₂CH₂CH₂)₂NH₂

Verified step by step guidance

Identify the functional group in the compound. In this case, the compound contains an amine group (-NH₂), which is a functional group characteristic of amines.

Determine the structure of the compound. The formula (CH₃CH₂CH₂CH₂)₂NH₂ indicates that there are two butyl groups (CH₃CH₂CH₂CH₂-) attached to the nitrogen atom.

Name the alkyl groups attached to the nitrogen atom. Since both groups are butyl groups, the prefix 'di-' is used to indicate that there are two identical groups.

Combine the alkyl group name with the suffix '-amine' to indicate the presence of the amine functional group. The name will reflect the two butyl groups and the amine group.

Ensure the name follows IUPAC naming conventions, and check for any additional rules or adjustments needed for clarity or correctness.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Alkyl Groups

Alkyl groups are derived from alkanes by removing one hydrogen atom, resulting in a hydrocarbon chain. In the compound (CH₃CH₂CH₂CH₂)₂NH₂, the (CH₃CH₂CH₂CH₂) part represents a butyl group, which is a four-carbon alkyl chain. Understanding alkyl groups is essential for naming organic compounds as they form the backbone of many structures.

Amines

Amines are organic compounds that contain a nitrogen atom bonded to one or more alkyl or aryl groups. In the given compound, the presence of the -NH₂ group indicates that it is a primary amine, where the nitrogen is attached to two butyl groups and one hydrogen atom. Recognizing the functional groups in a compound is crucial for proper nomenclature.

IUPAC Nomenclature

IUPAC nomenclature is a systematic method for naming chemical compounds based on their structure and functional groups. For the compound (CH₃CH₂CH₂CH₂)₂NH₂, the name would be dibutylamine, reflecting the two butyl groups attached to the nitrogen. Familiarity with IUPAC rules is vital for accurately identifying and communicating the names of chemical substances.
