Chapter 7, Problem 48QRT

Interpretation Introduction

Interpretation:

Table which includes all the types of noncovalent interactions, its strength and example for each has to be given.

Concept Introduction:

Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the functional group present in the molecule.

Types and strength of intermolecular forces in decreasing order:

$\text{Ionic}\text{>}\text{Hydrogen bonding}\text{>}\text{Dipole-Dipole Interactions}\text{>}\text{Vander}\text{Waals}\text{dispersion}\text{force}$

Ionic Interactions: The attractive force that holds two ionic compounds together with the help of ion-ion interactions is called as ionic interaction force

The positive charge end of one molecule is attracted to the negative charge of a neighboring molecule.

Hydrogen bonding: The attractive force that holds two polar molecules (containing Hydrogen and highly electronegative atom, such as N, O, or F) is called as hydrogen boding. This is also called as intermolecular hydrogen bonding.

The hydrogen bonding takes place within a molecule is called as intramolecular hydrogen bonding.

Dipole-Dipole Interactions: The attractive force that holds two polar molecules with help of dipole moment present in them is called as Dipole-Dipole Interactions.

The partial positive charge end of one molecule is attracted to the partial negative charge of a neighboring molecule.

Induced Dipole - Induced Dipole Forces: The attractive force that holds two nonpolar molecules with help of temporary dipole moment present in them is called as induced dipole-induced dipole forces.
