Question

In the protonation of H20, change occurs in
(1) Hybridisation state of oxygen
(2) Shape of molecule
(3) Hybridisation and shape both
(4) None​

Answer 1

Answer:

I think

shape of a molecule{2}

Answer 2

"In the protonation of $H_20$ , change occurs in the shape of the molecule.

Option (2).

Explanation:

• In chemistry, protons are hydrogen ion molecules. Water is the basis for all life processes.

• Protonation involves the addition of a proton to an atom/molecule/ion.

• It results in the formation of acid. When a proton is added to the water molecule, it results in the formation of hydronium ions.

       $H_2O + H ^+ \rightarrow H_3O^+$

• Hydronium ions contain three hydrogen atoms.

• During protonation, the nucleophilic center is attacked by a proton (hydrogen).
