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.**
\(\Rightarrow\)

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 alk**ane.**

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!

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)

Thank you! ^^

Hoping more .........

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.

how to remember functional group???

Log in to reply

A lot of practice will help you memorize the functional groups :D . That's what I did !

Hahah, yes, I suppose.
