The changes occur in reaction are the bond in H₂ is broken, and new bonds are formed between hydrogen and oxygen atoms and each electron associated with a hydrogen atom is shared with an oxygen atom.
What is hydrogen bond?
Hydrogen bond is a type of chemical bond which is formed between the hydrogen atom and more electronegative atom due to high dipole interaction.
Given chemical reaction is:
2H₂ + O₂ → 2H₂O
- In the above reaction hydrogen nucleus not loses proton inspite of that it was broken and new bond formation takes place in water.
- Oxygen atom doesn't gain electron inspite of that oxygen atom attracted electrons of hydrogen atoms.
- In the water molecule each electron of both hydrogens is shared with an oxygen atom.
Hence in the given equation bond of hydrogen molecule broke and new bond formation takes place and each electron of hydrogens is shared with an oxygen atom.
