Question

Which substance has the highest boiling point? why? (hint: they are all nonpolar.)

among CH₄, CH₃CH₃, CH₃CH₂CH₃, and CH₃CH₂CH₂CH₃, ___will have the highest boiling point because it has ____, indicating stronger

Answer 1

CH₃CH₂CH₂CH₃ has the highest boiling point among the listed nonpolar substances due to having the largest molar mass and consequently stronger London dispersion forces.

Step-by-step explanation:

Among the substances CH₄, CH₃CH₃, CH₃CH₂CH₃, and CH₃CH₂CH₂CH₃, CH₃CH₂CH₂CH₃ will have the highest boiling point because it has the largest molar mass, indicating stronger London dispersion forces.

As these compounds are all nonpolar, boiling point primarily increases with molecular size and mass due to the increased strength of dispersion forces.
