Explain the structure of Hydronium ion.
Advertisements
उत्तर
Structure of hydronium ion: Hydronium ions (H3O+) are formed when a hydrogen ion released from acid combines with water molecules.
Oxygen atom in water molecule attains an octet by forming two single covalent bonds with two hydrogen atoms but it still contains two lone pairs of electrons.
H3O+ is formed when the oxygen atom in water molecule donates a lone pair of electrons to a hydrogen ion thus establishing a coordinate bond between the oxygen atom and the hydrogen ion.

State the reasons, why carbon cannot
- Lose four electrons to form C4+ cation and
- Gain four electrons to form C4- anion.
How does carbon overcome this problem to form compounds?
