Are you struggling with organic chemistry? Download my free ebook "10 Secrets To Acing Organic Chemistry" here: leah4sci.com/or...
leah4sci.com/or... presents: Naming Straight Chain Alkanes
This video is Part 4 in the Naming Organic Compounds series
This video shows you how to name organic molecules with branched substituents showing you the 'long' way for each and the accepted abbreviations such as isopropyl, sec-butyl, isobutyl and tert-butyl
Many students struggle with naming because they attempt to come up with the entire name at once and often wind up missing a piece or two. After this series you won't have that problem anymore

when dealing with separate substituents, alphabetical order puts ethyl before methyl. However, when dealing with a substituent ON another substituent, you have to name the sub before the parent. When methyl is ON ethyl, you name it (1-methylethyl) to show that methyl is ON ethyl at position 1

@adisomstreamiiyear3533 8 лет назад

At 3:07 in the video when u have 4-(1-methylethyl) Octane, i thought because of alphabetical order it would be 4-(ethyl-1-methyl) Octane.

@allensmith342 4 года назад

Same confusion here. In an earlier video she said to arrange the constituents in alphabetical order ignoring the "tri." Now the priority has apparently changed without explanation. If you figured this out, any help would be appreciated.

@alexswarbrick984 4 года назад

She's right in the video. It should be 1-methylethyl. The main substituent chain is the ethyl as it is the longer chain and thus goes as the suffix. The prefix is the methyl as it branches off from the main ethyl 'backbone' so to speak. Just as you have the isopropyl group branching off from the octane, if you zoom in on this part of the molecule you have methyl branching from the ethyl part of this chain. Hopefully this helps anyone who's a little unsure.

@Leah4sci 3 месяца назад

alphabetical order applies to multiple substituents. However in a situation like this when you have a substituent ON a substituent, you have to name it as 'sub on parent' in this case it's ethyl ON methyl

@Leah4sci 8 месяцев назад

The substituent chain must start at the carbon attached to the parent chain. This means you cannot have a propyl due to the middle of the prop connecting the sub to the parent.

I echo all the positive vibes on this post. You make ORGO understandable, challenging and dare I say it, even fun. Question. On the example with the answer: 4-(1-methylethyl) I was under the impression that 1 is considered the default if no number is stated. If so, is it necessary to have 1 in the answer? Also, why is methylethyl not in alphabetical order? Thank you again for a great series of ORGO videos.

@Leah4sci 3 года назад

Thanks so much for your kind words. And YES! to orgo being fun!!! These are excellent questions! It’s always better to include more information than less. 1 would be considered the default in the case of having a priority functional group on carbon 1 of the parent chain. However, when naming these branched chain substituents, it’s the standard to include that 1. Secondly, the reason that methyl is stated before ethyl is because the methyl is a branch off of the ethyl. It’s a ‘substituent off of a substituent’. And substituents are always named in front of their parent chain.

I have a question about the example that starts at 2:00. Why wouldn't that molecule be 5-ethyl-2-methyloctane? If you start from the left of the molecule and curve down, that also gives you a parent chain of 8-> octane. But this gives you 2 substituents rather than 1 like you have. Isn't the rule choose the parent that will give you the most substituents??
