So the question asks, which is the following has the highest boiling point? so we're given two hexanone, two pentanone, butynoic acid, three methyl two butanone.
00:12
So options a, b, and d, just right here.
00:18
Options a, b, and d are going to have very similar boiling points because they all have some sort of r group and r prime group that's different with a carbonyl.
00:31
So they're all going to possess this carbonyl right here.
00:34
However, with option c, we can see that there is butyanoic acid.
00:41
And with butynoic acid, there's going to be four carbons.
00:53
And this is the only group that has this carboxic acid in which if we were to have a conjugate base, we can interchange these two double bonds.
01:05
Also, what this carboxic acid has, that does...
