Question

a single water molecule composed of one oxygen atom and two hydrogen atoms is held together by bonds. which of the following statements best describes those bonds?
electrons are shared unequally, with the oxygen pulling more than the hydrogens
electrons are shared equally between the oxygen and hydrogen atoms
electrons are shared unequally, with the hydrogens pulling more than the oxygen
electrons are shared equally between the two hydrogen atoms

Explanation:

Oxygen is more electronegative than hydrogen. In a water molecule ($H_2O$), the oxygen - hydrogen bonds are polar covalent bonds. This means electrons are shared unequally between the oxygen and hydrogen atoms, with oxygen pulling the shared electrons more strongly due to its higher electronegativity.

Answer:

Electrons are shared unequally, with the oxygen pulling more than the hydrogens
