1. What is the name of the intermolecular force caused by an instantaneous dipole in each below particles?

a)ionic attraction b)dispersion forces c)covalent bond d)hydrogen bond

2. For each of the following compounds, indicate which intermolecular force is the most important.

a)FCN b)HCN c)C2H6 d)CH3OH

Solutions

Expert Solution

1. Dispersion forces are the weakest intermolecular forces, a temporary attractive force arising when the electrons in the molecule are oriented in such a manner so as to create a dipole. Among the given forces, only dispersion force is caused by an instantaneous dipole. Hence, option (b) will be the correct answer.

The other options given will not be valid because non of them is related to a dipole.

2. The intermolecular forces can be best explained by drawing the Lewis dot structures, which is shown in the given image.
