Naming Amines
Ever wondered how scientists name those nitrogen-containing compounds in medications? Amines are classified by the number of alkyl chains attached to the nitrogen atom: primary amines (one alkyl chain), secondary amines (two alkyl chains), and tertiary amines (three alkyl chains).
For common naming, amines are named as alkylamines. Simply list the alkyl groups attached to the nitrogen in alphabetical order followed by "amine." For example, CH₃-CH₂-NH₂ is ethylamine, while CH₃-NH-CH₃ is dimethylamine.
In IUPAC naming, amines are named as alkanamines. The longest carbon chain is identified, numbered to give the amine group the lowest possible number, and the -e in the alkane name is replaced with -amine. For secondary and tertiary amines, the N-alkyl groups are specified using "N-" prefix.
Chemistry Tip: When amines appear as branches in molecules with oxygen-containing functional groups, they're named as "amino" , "N-alkylamino" , or "N,N-dialkylamino" groups.
When practicing, try naming compounds both ways: CH₃-CH₂-NH₂ is ethylamine (common) or ethanamine (IUPAC). You'll get the hang of it quickly!
Ammonium Salts and Amides
When amines gain an extra hydrogen or alkyl group, they form ammonium salts with positive charges. These salts are named by identifying both the positive ammonium ion and the negative counterion—like ethyldimethylammonium chloride.
Pharmaceutical companies often name amine salts differently, referring to the parent amine followed by the acid used to make the salt. For example, when hydrochloric acid (HCl) is used, the products are called amine hydrochlorides.
Amides are another important nitrogen compound, classified as primary, secondary, or tertiary based on nitrogen substitution. For naming amides, replace the "-oic acid" or "-ic acid" ending with "-amide." For instance, CH₃-CH₂-C-NH₂ is propanamide (IUPAC) or propionamide (common).
Remember: When alkyl groups are attached to the nitrogen in amides, use the "N-alkyl" prefix before the amide name, as in N-methylacetamide.
The amide derived from benzene gets a special name: benzamide. When you understand these patterns, you'll find naming these compounds much easier!
Naming Practice Examples
Ready to test your skills? Let's look at some examples to reinforce what you've learned about naming amines and amides.
Common names for amines focus on identifying all alkyl groups attached to nitrogen. For example, CH₃CH₂CH₂-NH-CH₂CH₂CH₃ is dipropylamine, while CH₃CH₂-N(CH₃)-CH₂CH₃ is triethylamine. Remember that for secondary and tertiary amines, list all groups alphabetically before "amine."
Aromatic amines have special names too—the simplest is aniline . Adding alkyl groups to the nitrogen gives compounds like N-methylaniline. Cyclic structures follow similar patterns, with cyclohexylamine having an -NH₂ group on a cyclohexane ring.
Pro Tip: When practicing amine naming, first identify the number of alkyl groups attached to nitrogen to determine if it's primary, secondary, or tertiary—this will guide your naming approach!
For functional group naming, remember that -NH₂ groups on carboxylic acids create amino acids, like 3-aminopropanoic acid. These compounds are building blocks of proteins and essential to life itself!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
