Concept:

Problem: 2-Butanone has ________ 3-pentanone because ______________1) a higher boiling point than; 3-pentanone is the larger molecule 2) a lower boiling point than; 3-pentanone is a larger molecule 3) approximately the same boiling point as; molecular size isn't an is 4) approximately the same boiling point; because the hydrogen bend the same in both molecules

FREE Expert Solution

We’re being asked to rank the given compounds in order of boiling point.


Recall that the boiling and melting point of a compound depends primarily on its mass, branching and intermolecular forces.


A higher mass means a higher boiling point. A more branched molecule will have a lower boiling point.
