Homework Answers
Compound in option C will have lowest boiling point because it is not a polar compound (like compounds in option A B and D) so it does not have dipole-dipole attraction forces between molecules also it is smaller in size than compound in option E so it will also have smaller Londen-forces between molecules .
Option C is answer.

Identify the compound with the lowest boiling point. A) CH3OCH3 B) CH3CH2CH3 C) CH3CHO D) (CH3)2O E) CH3CN * I need help understanding why the answer is B, when E has a lower molar mass. Also, I was under the impression that linear molecules such as B, have increased dispersion forces, and would ultimately have a higher boiling point.
