Question

Why is boiling point for carbon tertrachloride igher than methanol?

Answer 1

Carbon tetrachloride looks like this

Cl
Cl-C-Cl
Cl

Whereas methane looks as so,

H
H-C-H
H

In structure/geometry, they’re the exact same. They have the same surface area, and neither one is polar.

The only attribute to the difference in boiling points is the total molecular weights of the atoms

CH4 is MUCH lighter than CCl4, making the molecules easier to float around.
