Molecular Matters Polar and Non-Polar Solids

The video tutorial explains molecular solids, which are solids with molecules as constituent particles held together by intermolecular forces. These are classified into non-polar, polar, and hydrogen-bonded molecular solids. Non-polar molecular solids, like noble gases and non-polar molecules, are soft, have low melting points, and are poor conductors. Polar molecular solids, such as hydrogen chloride and solid ammonia, have strong dipole-dipole interactions, are generally soft, have higher melting points, and are non-conductors of heat and electricity.

What are molecular solids and how are they classified?

Describe the characteristics of non-polar molecular solids.

What interactions hold polar molecular solids together?

Provide examples of polar molecular solids and explain their properties.

How do the properties of polar molecular solids differ from those of non-polar molecular solids?
