Alright, guys, let's take a look at the example that was left for us in terms of naming. So this was a long structure, remember? Look for the longest carbon chain, the longest carbon chain is obviously this chain here. Remember, you want to count from the end closest to the substitue int whatever didn't get counted, which in this case, is that metal counting from either way gets us there. Because if you go here 12345 carbon five would have substitue int if you go here. 12345 again it has a substitution. So numbering either way is fine. So we'll say this is 678 and nine nine Carbons is called no name and the metal group is on carbon number five. So this one was not as bad as the previous two. So this would just be five metal known. So we've gone over different scenarios. Go to the next page and see if you can tackle the next naming set. Use the same principles that we have applied now to name the next group of compounds, come back and see how I approach them
