Which of the following bonds is weakest?
A) between two oxygen atoms within molecular oxygen
B) between the opposite ions, sodium and chloride
C) between the oxygen and hydrogens within a water molecule
D) between two water molecules
E) between the hydrogens within molecular hydrogen

Question

Quizplus · Accepted Answer

The bond between two water molecules (known as a hydrogen bond) is weaker than the other bonds listed. The bond between two oxygen atoms in molecular oxygen is a double bond and is therefore stronger. The ionic bond between sodium and chloride ions is also strong because of the attraction between opposite charges. The bond between the oxygen and hydrogens within a water molecule is a covalent bond, which is stronger than a hydrogen bond. The bond between the hydrogens within molecular hydrogen is also a covalent bond and is stronger than a hydrogen bond.
