Explanation:
Hydrogen bonding is an intermolecular force of attraction between two molecules. It is a special type of dipole-dipole attraction.
In hydrogen bonding, the hydrogen on one molecule binds with an electronegative atom on another molecule usually oxygen, nitrogen and fluorine.
The simple electrostatic attraction leads to strong intermolecular interaction between two molecules.
For the formation of hydrogen bond, a hydrogen atom must be bonded to more electronegative specie usually N, O and F
In H₂O and H₂O₂ ; hydrogen bonds with Oxygen
CH₃NH₂; hydrogen is attached to nitrogen
HF; hydrogen is attached to fluorine
CH₃OH; hydrogen is attached to oxygen
The reduction of a less active metal by a more active one is called metal displacement reactions. For example:
Fe + CuSO4 → FeSO4 + Cu
<h3>What is metal displacement reaction? </h3>
Displacement reactions is a reaction which includes a metal and the compound of a other metal. A more reactive metal will push or displace out a less reactive metal from its compound in this displacement reaction. The metal which is less reactive left uncombined after the reaction.
As we know that, electrons are the basis of the chemical reactions. If chemical compound or element A is more easily oxidized than B, then according to the terms of the activity series, the elements which are more easily oxidized can react with more chemicals, since they are able to act as a reducing agents for more chemicals.
Since, Metal ions are positively charged ions as they lose electrons. Some metals give up their electrons more readily than others and become more reactive.
Thus, we concluded that the reduction of a less active metal by a more active one is called metal displacement reactions. For example:
Fe + CuSO4 → FeSO4 + Cu
