Question

7. List all the intermolecular forces that exist between molecules (or formula units) in each of the following. CH3Cl H2 HCl NH3 HF CH3OH C2H4

Answer 1

Dispersion force exists in all

1)

CH3Cl

This is polar in nature

So, forces will be:

Dipolar interaction

Dispersion forces

2) H2

This is non polar in nature

So, forces will be:

Dispersion forces

3)HCl

This is polar in nature

So, forces will be:

Dipolar interaction

Dispersion forces

4)NH3

This is polar in nature and can form hydrogen bonding

So, forces will be:

Hydrogen bonding

Dipolar interaction

Dispersion forces

5)HF

This is polar in nature and can form hydrogen bonding

So, forces will be:

Hydrogen bonding

Dipolar interaction

Dispersion forces

6)CH3OH

This is polar in nature and can form hydrogen bonding

So, forces will be:

Hydrogen bonding

Dipolar interaction

Dispersion forces

7)C2H4

This is non polar in nature

So, forces will be:

Dispersion forces
