Question

4. Hydrogen bonds, ionic bonds, dipole-dipole attractions, dispersion forces are types intermolecular forces.Indicate the major type of intermolecular forces that occur between particles in the following substances: 6 pts(a) OBr2 =(b) LICI(c) H20 -(d) HBr -(e) CHCI) =( 1Br =

Answer 1

a) Dipole-Dipole

b) Ionic Bond

c) Hydrogen Bond

d) Dipole-Dipole

e) Dipole- Dipole

f) Dispersion Forces

Step-by-step explanation:

Here, we want to get the type of intermolecular forces that exist in the given molecules

Hydrogen bond exists when we have hydrogen being bonded to highly electronegative atoms.

Ionic Bonds exist between electropositive and electronegative atoms in a molecule

Dipole-Dipole interaction is a weak type of intermolecular force arising from induced diploes

Dispersion forces forms from temporary dipoles and they are weak

The molecules and their type of intermolecular forces are as follows:

`\begin{gathered} a\text{ \rparen OBr}_2\text{ - Dipole - Dipole Interaction} \\ b)\text{ LiCl - Ionic Bond} \\ c)\text{ H}_2O\text{ - Hydrogen Bond} \\ d)\text{ HBr - Dipole -Dipole Interaction} \\ c)\text{ CHCl}_3\text{ - Dipole-Dipole Interaction} \\ f)\text{ IBr - Dispersion Forces} \end{gathered}`

We should note that Dipole-Dipole forces occur between atoms that are electronegative
