Which of the following compounds has the highest boiling point?
A) 2-butanone
B) 2-heptanone
C) 2-hexanone
D) 2-pentanone

Question

Quizplus · Accepted Answer

The boiling point of a compound depends on its molecular weight, size, and intermolecular forces. As we move from 2-pentanone to 2-heptanone, there is an increase in the molecular weight and size of the compounds, which leads to an increase in the boiling point. Additionally, the longer carbon chains in 2-heptanone lead to stronger van der Waals forces between the molecules, which also increases the boiling point. Therefore, 2-heptanone has the highest boiling point among the given options.
