Simple Alkane Nomenclature!

So the core of organic chemistry (on a basic level) is naming the compounds!

So, first of all, we will be looking at some types of alkanes. I hope you're reasonably familiar with what this represents. Alkane Alkane.

And the first question you should be asking is how many carbons are there? Just as a review, the endpoint of every line represents a carbon. \Rightarrow Six Carbons Six Carbons

And so, we have six carbons and all single bonds, and now... you are ready to name this molecule!

Before I name this, I'll give you some of the prefixes.

If you have... 1 Carbon \Rightarrow the prefix is Meth.

2 Carbons \Rightarrow Eth.

3 Carbons \Rightarrow Prop.

4 Carbons \Rightarrow But.

and after 5, it kinda becomes easier.

5 Carbons \Rightarrow Pent.

6 Carbons \Rightarrow Hex.

7 Carbons \Rightarrow Hept.

8 Carbons \Rightarrow Oct.

9 Carbons \Rightarrow Non.

10 Carbons \Rightarrow Dec.

And just for the sake of curiosity, I will go up to 20.

11 Carbons \Rightarrow Undec.

12 Carbons \Rightarrow Dodec.

13 Carbons \Rightarrow Tridec.

14 Carbons \Rightarrow Tetradec.

15 Carbons \Rightarrow Pentadec.

16 Carbons \Rightarrow Hexadec.

17 Carbons \Rightarrow Heptadec.

18 Carbons \Rightarrow Octadec.

19 Carbons \Rightarrow Nonadec.

20 Carbons \Rightarrow Icos. Twenty is a bit different but there it is.

So, if there are no double bonds or triple bonds etc. Also, just carbons and hydrogen, so no oxygen or whatever else. THEN we're dealing with an alkane.

Now, you have 6 carbons all in a single bond \Rightarrow Take the hex for six and because this is an alkane, we take the -ane from alkane.

And we get, hexane!

Hopefully, you found that interesting. Although, this is just the basics of the nomenclature that IUPAC came up with.

^^ Hope you enjoy reading this!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Nice! It seems I am interested to post some of my notes too for chemistry.

Nice Work Vishnuram ! Keep It Up.

(And thanx for you considered my comment for nomenclature posts)

Yeah, haha. I'll do a bit more of alkane nomenclature before going onto other functional groups. ^^ Maybe some problems too. X'D

WAiting for the problems.
