Select the compounds in each group that are isomers and specify whether they are constitutional isomers or stereoisomers.
So, now let's go ahead and figure out the ike words that we have in this trio, so guys we've got just looking at this we've got 1, 2, 3, 4, 5, 6 carbons here, so it's going to give us C6H14 since we don't have any IHD, this next one guys it's actually just the first one just rotated, right? Notice we've got a methyl group on our pentane on and the methyl group goes off our number two carbon, same thing over here, so this is actually C6H14 and these are going to be the same, and then over here we've got 1, 2, 3, 4, 5, 6 but now that methyl group is on our number 3 carbon, right? But it still C6H14 and these, right? in addition to these are the same, they're going to be constitutional isomers squeezed in there, alright? So, let's move on.
