Question

What are the intermolecular forces of $CHF_3,OF_2,HF,$ and $CF_4$ ?

Answer 1

Hint : To solve the given question, we should have information about intermolecular force and type of intermolecular forces.
Intermolecular force is the force of attraction or repulsion between the interacting particles ( atoms, ions and molecules ).

Complete Step By Step Answer:
Step-1 :
In case of a molecule, there are many different types of forces present but the strong ones are given the main priority.
Step-2 :
The force of attraction among the polar molecules are Dipole - Dipole interactions. This force can be originated by dipole and polar molecules have permanent dipole. Here, $CHF_3$ is a dipole and thus has dipole - dipole interaction.
Step-3 :
Dispersion forces or London forces are the force of interaction between the induced momentary dipoles. It operates only over very short distances. The momentary dipoles induced dipoles in the neighbouring molecule. $OF_2$ shows London dispersion forces.
Step-4 :
Hydrogen bond is a bond present between hydrogen and a small electronegative element like Oxygen and Fluorine. is present in liquid state due to the presence of intermolecular H-bond.
Step-5 :
Dispersion forces or London forces are the force of interaction between the induced momentary dipoles. It operates only over very short distances. The momentary dipoles induced dipoles in the neighbouring molecule. $CF_4$ shows London dispersion forces.

Note :
In case we have to look for the force of interaction, we have to look to the different types of molecules and find each type of interaction they can have. The types of Intermolecular forces are dipole - dipole, Dipole - Induced Dipole, Ion - Dipole, Ion - Induced Dipole, Dispersion forces or Hydrogen Bonding.
