Question

Select the correct statement about the hydrogen bonds in water.

• A. The hydrogen of one molecule bonding to the hydrogen of another molecule.
• B. The oxygen of one molecule bonding to one of the hydrogen of that molecule.
• C. The hydrogen of a water molecule bonding to the nitrogen of another.
• D. The hydrogen of one molecule bonding to the oxygen of another molecule.
• E. None of the above.

Answer 1

The correct option is D The hydrogen of one molecule bonding to the oxygen of another molecule.

The covalent bond between oxygen and hydrogen atom in a water molecule has polar nature as oxygen is more electronegative than hydrogen. This imparts hydrogen atom partial positive and oxygen atom partial negative charge. A hydrogen bond is defined as electrostatic attraction between positively charged hydrogen atom in water and unpaired electrons from another atom, either in the same (intramolecular) or in a different (intermolecular) molecule. Thus, the correct answer is option D.
