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..
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.
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 the prefix is Meth.
2 Carbons Eth.
3 Carbons Prop.
4 Carbons But.
and after 5, it kinda becomes easier.
5 Carbons Pent.
6 Carbons Hex.
7 Carbons Hept.
8 Carbons Oct.
9 Carbons Non.
10 Carbons Dec.
And just for the sake of curiosity, I will go up to 20.
11 Carbons Undec.
12 Carbons Dodec.
13 Carbons Tridec.
14 Carbons Tetradec.
15 Carbons Pentadec.
16 Carbons Hexadec.
17 Carbons Heptadec.
18 Carbons Octadec.
19 Carbons Nonadec.
20 Carbons 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 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!
