The correct answer is Option D) Dissimilar in hybridization for the central atom with different structures
In \({NO_3 , H = \frac{1}{2} [ 5 + 0 - 0 + 1 ] = 3}\)
Thus, in \({NO^{-}_{3}}\), the central atom is sp2 hybridized and it has trifocal planar geometry.
In \({H_3 O^{+}}\) ,
\({H = \frac{1}{2} [ 6 + 3 - 1 +0 ] = 4 }\)
Thus, \(O\) is \(sp^3\) hybridised in \({H_3O^{+}}\) and \({H_3O^{+}}\) has pyramidal geometry due to the presence of one lone pair of electrons.
The correct answer is Option D) Dissimilar in hybridization for the central atom with different structures
In agriculture, nitrates are utilised as fertilisers due to their high solubility and biodegradability. Salts of ammonium, sodium, potassium, calcium, and magnesium are the principal nitrate fertilisers. For this use, many billion kilogrammes are generated each year.
The most common application for nitrates as oxidising agents is in explosives, where the quick oxidation of carbon compounds releases significant amounts of gases.
To get rid of air bubbles in molten glass and various ceramics, use sodium nitrate. Some metals are hardened using salt mixtures that are molten.
Nitrocellulose was also utilised to create films from nitrate. Nitrates, sometimes referred to as nitrovasodilators in the medical sector, are utilised in the prevention and treatment of heart attacks. Hydronium ions can be found in creams and gels for the skin. They may be used to treat skin disorders including acne, rashes, redness, and others while also restoring the skin's health.

Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
