In this video, we're gonna talk about the way of naming CYO Alkanes. Now we're gonna say the name, the rules for naming cyclicalk or Cyclo alkanes are very similar to naming Al Canes with substituents. Here. Our naming convention will be looking at the location of each substituent and because it's a cyclic Alcaine or cyclo Alcaine, the parent chain is named as a Cyclo parent chain. So now that we know the basic naming structure, let's move on to the next video where we start naming different types of CYO Alkane compounds.

Now here in this example, question, it says, determine the systematic name of the following Alcaine. So to do that, we're gonna employ the following steps. So step one, it says assign name to the Alcaine ring. The ring here will serve as the parent according to its prefixes. Now you're gonna add the prefix Cyclo to the name of the Alcaine ring because it's no longer just an alkane. It's a cyclic Alcaine. So we're gonna use Cyclo. Now, step two, you're gonna sign names to all the substituents on that ring. Step three, start numbering the chain from the closest substituent. Now, if only one substituent location is not necessary if I tie between substituents, compare the clo the next closest substituent if still a tie number in alphabetical order. Now, from our previous videos, in terms of naming our cans with substituents, we'd use steps 4 to 6. So repeating the same steps from that previous topic number. This has to do with giving a location for the substituents. It has to do with naming substituents alphabetically and then remember that we use commas to separate numbers from one another and we use dashes to separate letters and numbers from one another. Now, if we take a look here, we have a one, well, we have 123456 carbons. Long terms of our cyclic Alcaine six carbons for an alkane is hexane, but it's not just hexane, it's a cyclic hexane. So we use the prefix cyclo. So this is a cyclohexane ring and attached to it is a three carbon alko group. Since the bond is at one of the ends of this three carbonel keel group, it represents propol. Now, here there's only this one substituent. So you don't need to give its numerical location because wherever it is located, that's where carbon number one will be in this case. So here we'd say that this is called prop cyclohexane. This will be the name of this particular cyclical canine with its substituent.
