For each pair of compounds below, determine whether they are identical compounds, constitutional isomers, stereoisomers, or different conformations of the same compound:
Hey guys. So, here we have these two six membered rings with two substituents on them, okay? we need to determine their relationship to each other, so what you can notice is that we have methyls at positions one and three, for both of them, and notice that if we try the name this compound we would have to identify it as a 13 dimethyl cyclohexane but where they differ is that. Notice at carbon 3 here we have a methyl coming off on a wedge but at carbon 1 on the Left molecule is coming off on a wedge but on the right is actually coming off on a dash, so let's say we try to determine the relationship between our substituents as far as cis and trans goes, on the left, what would you call this one? you say that they're cis. Now, what about the one on the right? trans, right? Because they're on different sides, so now that we know that these two molecules they're are six membered rings they both have two methyl substituents coming off the same exact positions, right? 1,3 and 1,2, excuse me, 1,3 1,3. All that means that these two molecules have a different arrangement in space and what we call that is stereo isomers, right? Now, let's say we had one methyl coming off at position 2 instead and we compared a 1,2 verse a 1,3. This relationship would mean constitutional isomers, okay? But that's not what we have here, what we have is just the relationship of stereo isomers because they're connected the same, the only difference is that one is cis and one is trans, okay? But if we wanted to name them they would both be 1,3 and then dimethyl cyclohexane, okay? With the cis and trans indicated. Alright guys, so hopefully this makes sense just remember that we have to look at their connectivity and then the atoms and try to think of their molecular formers. Alright guys. So, just let me know if you have any questions.
