Water can dissolve more substances than any other liquid because

The correct option is: it is dipolar in nature.

Explanation:

Water (${\text{H}}_2\text{O}$) is often referred to as the "universal solvent" because it can dissolve more substances than any other liquid. This unique property is primarily due to its dipolar nature (polar molecule).

1. Structure and Polarity of Water:
A water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom in a bent shape. Oxygen has a higher electronegativity than hydrogen, meaning it attracts the shared electrons more strongly. This creates a partial negative charge (${\delta }^{-}$) near the oxygen atom and a partial positive charge (${\delta }^{+}$) near the hydrogen atoms, forming a dipole moment.

2. Dissolving Mechanism:
Because water molecules are dipolar, they interact strongly with both positively and negatively charged ions, as well as other polar molecules:

• Ionic Compounds (e.g., NaCl): The partial negative oxygen end of water attracts the positive sodium ions (${\text{Na}}^{+}$), while the partial positive hydrogen ends attract the negative chloride ions (${\text{Cl}}^{-}$). This hydration process disrupts the ionic lattice and dissolves the salt.

• Polar Covalent Compounds (e.g., Sugars, Alcohols): Water forms hydrogen bonds with polar functional groups, allowing them to dissolve easily.

Therefore, the dipolar nature of water gives it a high dielectric constant and electrostatic attraction capabilities, making it an extraordinary solvent.
