There are 3 important trends to consider.
The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. The influence of each of these attractive forces will depend on the functional groups present.Boiling points increase as the number of carbons is increased.Branching decreases boiling point.

Answer:
Dip the open end of the capillary tube in the finely powdered Benzoic acid. Fill the compound in the capillary tube to about a length of 1–2 cm by gently tapping the capillary. Attach the thermometer to a capillary tube using a thread.
