Sorry for being late guys, hahah... Been busy with valentine and stuff. Lul.

So far, we got to name alkanes which had **single** carbon chains.
Now, let's deal with something more complex.

Here we don't have a single carbon chain, it starts to **branch** off.
I went ahead and counted how many carbons there are in a **single** chain.

So what we do is look at the **longest** chain. In this case, it's the nice purpley chain.
Think of it like the **backbone** of our naming.

Hence, we have **nine carbons** $\Rightarrow$ we're dealing with a **nonane!**
**Non** for nine and **ane** because we're dealing with an alkane (we have all single bonds).

What's kind of *sticking off* our main carbon chain? It's another carbon (w/ three **hydrogens**)! True?

Maybe you might be tempted to say *methane*, but no... It's attached to **other things.**
But it would be right to use the *prefix: meth.*

And we (*IUPAC*) made it so that it would be called **methyl.** The **yl** from **methyl** means it branches off a **longer chain.**

Thus, let's call it... **methylnonane**, but there's one problem. This , however...

This is also methylnonane, true?

It goes according to what we did so far.What about this?

. And so on and so forth.So how would you name those things **differently?**
The way we do that is, number the carbons on your main chain, then look at which carbon # it is bonded to.

Our first molecule **third carbon on the main chain.** Hence, we call this... **3 - Methylnonane.**

What about this? **4 - Methylnonane.**

And you can try naming the last one. Hahha.
