Question

write the different types of hydrogen bond and explain this types​

Answer 1

Answer:

There are two types of H bonds, and it is classified as the following: Intermolecular Hydrogen Bonding. Intramolecular Hydrogen Bonding.

Explanation:

Properties of Hydrogen Bonding

Solubility: Lower alcohols are soluble in water because of the hydrogen bonding which can take place between water and alcohol molecule.

Volatility: As the compounds involving hydrogen bonding between different molecules have a higher boiling point, so they are less volatile.

Viscosity and surface tension: The substances which contain hydrogen bonding exists as an associated molecule. So their flow becomes comparatively difficult. They have higher viscosity and high surface tension.

The lower density of ice than water: In the case of solid ice, the hydrogen bonding gives rise to a cage-like structure of water molecules. As a matter of fact, each water molecule is linked tetrahedral to four water molecules. The molecules are not as closely packed as they are in a liquid state. When ice melts, this case like structure collapses and the molecules come closer to each other. Thus for the same mass of water, the volume decreases and density increases. Therefore, ice has a lower density than water at 273 K. That is why ice floats.
