Answer 1

Водородная связь это разновидность донорно-акцепторной связи 
Примеры - это вода, спирт и водка.Водородная связь образуется между электроотрицательными атомами, из которых хотя бы один имеет свободную электронную пару.

Answer 2

Examples of Hydrogen Bonding

Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is bonded to a highly electronegative atom and is also attracted to another electronegative atom. Here are some examples of hydrogen bonding:

1. Water Molecules (H2O): - In water molecules, hydrogen bonding occurs between the hydrogen atom of one water molecule and the oxygen atom of another water molecule. - This results in the unique properties of water, such as its high surface tension and specific heat capacity. - *Source:* 2. Ammonia Molecules (NH3): - Hydrogen bonding can also be observed in ammonia molecules, where the hydrogen atom is attracted to the electronegative nitrogen atom. - This leads to the formation of ammonia clusters due to hydrogen bonding interactions. - *Source:* 3. Hydrogen Fluoride (HF): - Hydrogen fluoride is another example where hydrogen bonding occurs between the hydrogen atom and the highly electronegative fluorine atom. - This results in the unique properties of hydrogen fluoride, such as its high boiling point compared to other hydrogen halides. - *Source:* These examples illustrate how hydrogen bonding plays a crucial role in determining the physical and chemical properties of various substances, impacting their behavior and interactions with other molecules.
