Chapter 11, Problem 51SCQ

(a)

Interpretation Introduction

Interpretation:

Among the given hydrogen halide, the one with largest  total intermolecular forces has to be identified.

Concept Introduction:

London dispersion force also called an induced dipole-induced dipole attraction is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.

Dipole-dipole interaction results when two dipolar molecules interact with each other through space, there occurs a partially negative charge of one of the polar molecules is attracted to the partially positive charge of the second polar molecule.

Ion-dipole interaction results of an electrostatic interaction between a charged ion and a molecule that has a dipole.

A hydrogen bonding is partially an electrostatic attraction between $\text{H}$ atom which is bonded to more electronegative atom such as $\text{N, O, or}\text{F}$ and another adjacent atom bearing a lone pair of electron

(b)

Interpretation Introduction

Interpretation:

Reason for the dispersion forces greater for $HI$ than $HCl$ has to be identified.
