  1. Question 1

    Q1. In a diagram showing a water molecule, the oxygen atom carries a partial negative charge due to which chemical property?

    • A) Ionic bonding
    • B) Electronegativity difference
    • C) Hydrophobic interaction
    • D) Van der Waals forces

    Answer: Electronegativity difference

    Explanation: Oxygen's higher electronegativity creates polar covalent bonds; ionic bonding is tempting but involves the complete transfer of electrons rather than sharing.
