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.

7) Which compound has the lowest boiling point? A) CH3CHO B) CH3CH2CHO C) CH3CH2OH D) CH3CH2CH2OH E) CH3COCHZ
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.
