Question

Identify the major type of intermolecular forces between the particles of each of the following:
a. $BrF$

b.$KCl$

c. $N{F}_3$

d.$C{l}_2$

Short answer

(a) Dipole-dipole attraction.

(b) Ionic attraction.

(c) Dipole-dipole attraction.

(d) Dispersion forces.

Step-by-step solution

Part(a) Step1 : Given information.

We have been given that,

$BrF$

We need to find the type of intermolecular forces between it's particles.

Part(a) Step2 : Simplify.

The intermolecular forces between its particles is dipole-dipole attraction.

• Occur between positive end and negative end of polar molecules.
• Weak intermolecular forces .

Part(b) Step1 : Given information.

We have been given that,

$KCl$

We need to find the type of intermolecular forces between it's particles.

Part(b) Step2 : Simplify.

The intermolecular forces between its particles is ionic bond.

• It is soluble in water due to ionic bond.
• In solid state they do not conduct electricity.

Part(c) Step1 : Given information.

We have been given that,

$N{F}_3$

We need to find the type of intermolecular forces between it's particles.

Part(c) Step2 : Simplify.

The intermolecular forces between its particles is dipole-dipole attraction.

• It is inorganic ,colorless, non-flammable.
• Used in semiconductor, LCD, solar panels, etc.

Part(d) Step1 : Given information 

We have been given that,

$C{l}_2$

We need to find the type of intermolecular forces between it's particles.

Part(d) Step2 : Simplify.

The intermolecular forces between its particles is dispersion forces.

• Occur between atom and molecules.
• Forces are attractive in nature.
• This forces depend on molecular weight.
