Answer
The compound on the left will have a higher boiling point because of the hydrogen bonding and larger surface area.
Work Step by Step
The compound on the left will have a higher boiling point because of the hydrogen bonding and larger surface area. It has a N-H, due to which there will be hydrogen bonding between the molecules. Moreover, the branches of the compound on the left are longer, hence have a larger surface area and higher boiling point.
