Question

Effect of h bonding on physical and chemical properties

Answer 1

Explanation:

Physical properties are governed by the intermolecular forces - forces attracting one molecule to its neighbours - van der Waals attractions or hydrogen bonds. Molecular substances tend to be gases, liquids or low melting point solids, because the intermolecular forces of attraction are comparatively weak.

Answer 2

General Effects of Hydrogen Bonding Since intermolecular hydrogen bonds bring molecules closer together, liquids increase in density. It requires energy to disrupt these bonds, so the liquids have a higher boiling point. Hydrogen bonds, though flexible, distort molecules into specific positions.
