Question

Choose the correct option(s) from the following regarding the solubility in water:

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

Hint:

- Polar solutes dissolve better in polar solvents like water.
- Charge and aromatic groups influence molecular polarity and water solubility.

Answer 1

The Correct Option is A, D

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.
