- Water is a polar molecule because of the asymmetric distribution of charge between the oxygen and hydrogen atoms of the water molecule.
- In a water molecule, the electrons shared between oxygen and hydrogen are attracted more towards the hydrogen atom.
- Non-polar compounds are highly soluble in water because of their strong interaction with water molecules.
- Aromaticity and charge of molecules influence their solubility in water.

The Correct Option is A, D
Solution and Explanation
Step 1: Analyzing statement (A).
Water is a polar molecule because oxygen is more electronegative than hydrogen, leading to unequal electron sharing and an asymmetric charge distribution. So (A) is correct.
Step 2: Analyzing statement (B).
Electrons are attracted more towards the oxygen atom, not hydrogen, due to higher electronegativity. Hence, (B) is incorrect.
Step 3: Analyzing statement (C).
Non-polar compounds are generally not soluble in water due to lack of interaction with polar molecules (like dissolves like). So (C) is incorrect.
Step 4: Analyzing statement (D).
Aromaticity and molecular charge affect the ability to interact with polar water molecules, influencing solubility. So (D) is correct.
Water is a polar molecule because oxygen is more electronegative than hydrogen, leading to unequal electron sharing and an asymmetric charge distribution. So (A) is correct.
