Welcome back, everyone give the OPEC names and condense structural formulas for the structural isomers of an L cane with the molecular formula C six H 14. So first of all, we're going to begin with an LK that has a total of six carbons in the longest continuous chain. And then we will keep shortening it. So 12345 and six. And because this is an L cane, we simply want to make sure that each carbon has a total of four bonds. So we're adding three hydrogens followed by two, another two, two, two and finally three. So in this case, we have a straight chain L cane. It is called hexane because the longest continuous chain of carbons has six carbons. Now, we want to draw our first structural isomer. And what we're going to do is someplace shorten the chain to five carbon atoms. So now we have CH three followed by CH two, three times and then CH three. Now the final carbon can be bonded to carbon number two or carbon, number three, right? Because essentially the structure is symmetrical, we can have two isomers here and we can achieve those isomers by virtual replacing the hydrogen atom at carbon number two, wet ch three. And this gives us pens what type of pens? While carbon number two is bonded to the methyl group. So that'd be two methyl pens. As we already know, we can get three muscle pens by simply replacing the hydrogen atom at carbon. Number three with the muscle group. Let's go ahead and to the structure. And instead of CH two, we're go, we're going to have Ch Bonne to CH three. And then we can simply name the structure, right. So that would be three meth insane. And we are done with pentane essentially, if we move the muscle group further, that'd be two methyl Penta again. Now we're going to draw a four numbered parent. So let's draw a four member chain starting with CH three. Then we will have S two, CH two and CH three. How many isomers can we form? Well, essentially, we need to add two carbons and we can add those two carbons as muscle groups bonded to carbon. Number two, this gives us 66 carbon atoms. So we simply want to remove the two hydrogen atoms. And we can see that we have a quaternary position for this structural isomer. We know that it is butane and it has two metal groups at position two. So that'll be 22 di meal and the parent is Beane. And of course, we can add another isomer in which the two methyl groups are bonded to carbons two and three. So that would be an additional isomer, we can begin by drawing C three, followed by two carbons finish with CH three. And now we are saying that OK, we are adding two methyl groups as branches bonded to carbons two and three. So as we can see each of those two carbon atoms, they need a one hydrogen, right? So essentially if we want to name it once again, it's bane. But now it has methyl groups bonded to carbons two and three. So that'd be 23 dimethyl be same. Now, can we shorten the chain to three carbon atoms? Well, essentially we cannot, right? Because we will still need to add three more carbons and that would make the parent chain with a total of four members. So that'll be it. We have got the five possible structural isomers.
