f. The complete structural formulas of propane, C$_3$H$_8$, and methanoic acid, HCOOH, are shown above.
(i)
In the table below, write the type(s) of intermolecular forces(s) that occur in each
substance:
Substance Boiling Point Intermolecular Attractive Force(s)
Propane 229 K
Methanoic acid 374 K
(ii)
Using principles of intermolecular attractive forces, explain why methanoic acid has a
higher boiling point than propane.
