Answer
The compound on the right will have a higher boiling point because of the larger surface area and hydrogen bonding.
Work Step by Step
The compound on the right will have a higher boiling point because of the larger surface area and hydrogen bonding. Both the compounds have hydrogen bonding. However, the compound on the right has a larger surface area because N is not a part of the ring but is bonded to the C and two Hydrogens. This gives it a larger surface area and hence higher boiling point.
