Considering intermolecular forces in the pure substance; which of these substances exists as a gas at 25 °C and 1 atm?

  1. (a) Ne
  2. (b) CH4
  3. (c) CO
  4. (d) CCl4

(a)

Interpretation Introduction

Interpretation: From the following which of the substance exist as gases at 250C and 1atm in pure state is 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 H atom which is bonded to more electronegative atom such as N, O, orF and another adjacent atom bearing a lone pair of electron

Explanation of Solution

Neon Ne has dispersion forces. CO have a permanent dipole moment.CC

(b).
