Regarding H₂O the wrong statement is

1.H₂O, also known as water, is indeed an exothermic compound, meaning that it releases heat when it undergoes a chemical reaction. This is due to the strong hydrogen bonding between water molecules, which stabilizes the molecules and releases energy when the bonds are formed.

2.Water is also an associated liquid, meaning that it forms clusters or aggregates of molecules due to the hydrogen bonding between them. This clustering behavior contributes to the unique properties of water, such as its high surface tension, viscosity, and ability to dissolve polar substances.

3.The central atom in a water molecule is oxygen, which is sp3 hybridized. This means that the oxygen atom in water has four electron orbitals arranged in a tetrahedral shape, with two of the orbitals containing lone pairs of electrons and the other two orbitals bonding with hydrogen atoms.

4.Water is an excellent solvent for ionic compounds due to its polar nature. The partial positive and negative charges on the hydrogen and oxygen atoms, respectively, attract ions and allow them to dissociate and dissolve in water. This property makes water essential for many biological and chemical processes.
